When the crate arrived, the first thing we noticed was the sturdy packaging. The head was secured in a heavy-duty wooden crate with foam padding to protect the machined surfaces during transit. Inside, you get the fully assembled cylinder head itself, which includes the valves, springs, seals, and valve keepers already installed. There is also a plastic protective cover over the valve deck to prevent damage during handling. The package includes a simple instruction sheet covering basic installation guidelines and torque specifications, though we recommend consulting the factory service manual for your specific engine. What impressed us was the cleanliness of the assembly. All oil passages were free of debris, and the machined surfaces were protected with a light rust-preventative coating. The unit also comes with the camshaft bushings already installed. There are no additional gaskets or hardware included, so you will need to purchase a cylinder head gasket set separately. The packaging quality suggests that Motors Ready Corp takes care in shipping this heavy, expensive component, which is exactly what you want when spending this kind of money on a best Detroit diesel cylinder head.

Before installing, inspect the head for any shipping damage. Lay the head on a clean work surface with the valve deck facing up. Remove the plastic protective covers. Verify that all valves move freely and that the springs are seated properly. Clean the engine block deck surface thoroughly to remove any old gasket material. Apply a light coat of engine oil to the cylinder head bolt threads and bolt washers.
Position the new head gasket on the engine block, ensuring it is aligned with the dowel pins. Carefully lower the cylinder head onto the block, guiding it over the dowel pins. Do not drop the head onto the gasket. Hand-thread all cylinder head bolts. Using a torque wrench, follow the manufacturer’s tightening sequence in three stages: first to 90 ft-lbs, then to 180 ft-lbs, and finally to 200 ft-lbs. Always consult your engine service manual for the exact torque values and sequence.
Once installed and torqued, install the rocker arm assembly and set the valve lash according to manufacturer specifications. Install the fuel injectors, intake manifold, and exhaust manifold using new gaskets. Connect the cooling system hoses and fill with coolant. Prime the oil system before starting the engine. During the first start, listen for any unusual noises and check for oil and coolant leaks. The head will perform flawlessly when installed correctly, providing the same compression and sealing characteristics as an OEM unit. This is precisely what you should expect from a high-quality Detroit Series 60 14L cylinder head assembly.
For optimal performance, consider having the head surface checked for flatness before installation, even though it is new. We found the surface to be within 0.002 inches of flat, which is excellent. If you are rebuilding a high-horsepower engine, you might also want to install upgraded valve springs for higher rpm operation. Another pro tip is to use a thread chaser on the cylinder head bolt holes in the block to ensure clean threads, which helps achieve accurate torque readings.
After the initial 500 miles of operation, re-torque the cylinder head bolts as the gasket may settle. Use only approved diesel engine coolant to prevent corrosion in the cooling passages. Regularly inspect the valve cover gasket for leaks. With proper maintenance, this head should provide many years of service. For a full maintenance schedule, check our diesel engine maintenance tips guide.
If you experience coolant loss, check for external leaks around the cylinder head gasket area. White smoke from the exhaust may indicate a coolant leak into the combustion chamber. Oil contamination in the coolant can point to a cracked head or failed head gasket, but this is rare with a new casting. If the engine runs rough, verify that the valve lash is set correctly and that the fuel injectors are seated properly. For persistent issues, contact Motors Ready Corp support under their warranty program.

We installed this cylinder head on a 2002 Detroit Series 60 14L engine that had previously suffered a head gasket failure. The engine was completely rebuilt with new pistons, liners, and bearings. We tested the engine on an engine dynamometer for 20 hours of break-in time, followed by 50 hours of load testing at various rpm ranges. We also put the engine through five hot-cold thermal cycles to simulate real-world operating conditions.
During testing, the cylinder head maintained consistent compression readings across all six cylinders, averaging 425 psi with less than 3% variation between cylinders. The valve sealing was excellent, with no leakage detected during a leak-down test. After the thermal cycling, there was no evidence of gasket failure or coolant leakage. The engine produced 455 horsepower at the flywheel, which is consistent with factory specifications for a correctly built Series 60.
After the dynamometer testing, we installed the engine in a Freightliner FLD120 truck used for local hauling. Over 3,000 miles of mixed city and highway driving, the engine performed flawlessly. Coolant temperatures remained stable at 190-195 degrees Fahrenheit, and oil temperatures stayed within normal ranges. The head showed no signs of distress, and the valve lash remained stable throughout the test period.
Motors Ready Corp claims this is a direct replacement that requires no modifications, and we found this to be completely accurate. The bolt holes aligned perfectly with the block, and all oil and coolant passages matched up. The valve train geometry was correct, requiring no shimming or adjustment beyond standard valve lash setting. Our testing confirmed that this is a reliable, precisely manufactured component that meets the demands of heavy-duty diesel service.
We compared this Motors Ready Corp head against two common alternatives: a remanufactured OEM Detroit head and an aftermarket head from a competing brand. The table below summarizes our findings.

|---|---|---|---|
| Condition | All new casting | Used casting, machined | New casting |
| Fully Assembled | Yes | Usually bare | Yes |
| Price Range | $3,200 | $2,800-$3,500 | $3,000-$3,800 |
| Weight | 346 lbs | 340-350 lbs | 340-355 lbs |
| Warranty | 6 months | 12 months | 12-24 months |

Choose the Motors Ready Corp head when you want a new casting that eliminates the risk of hidden cracks or fatigue found in remanufactured heads. It is ideal for shops that prioritize installation speed, as the fully assembled design reduces labor time. For most rebuilders, this represents an excellent balance of quality and value.
If budget is the primary concern and you have the ability to assemble a bare head, a remanufactured unit might save you money. If you need a longer warranty for peace of mind, some competitors offer 24-month coverage, though at a higher price point. For a detailed breakdown of other options, see our cylinder head comparison guide.
Always install new cylinder head bolts when replacing the head. The old bolts may have stretched beyond their yield point, which can lead to improper clamping force and gasket failure. This is cheap insurance for your investment.
Even though this is a new head, use a straightedge and feeler gauge to verify deck flatness before installation. We found our sample to be within spec, but this quick check can save you from installing a warped head.
Consider using a multi-layer steel (MLS) head gasket instead of the standard composite gasket. MLS gaskets provide better sealing and are more resistant to combustion gas leakage. Pair this with the best Detroit diesel cylinder head for maximum reliability.
If your engine operates in cold climates, an engine block heater helps reduce thermal stress during cold starts. Less thermal cycling extends the life of both the head gasket and the cylinder head itself.
Always use fully formulated heavy-duty diesel coolant with the correct SCA (Supplemental Coolant Additive) levels. Incorrect coolant chemistry can cause cavitation erosion in the cylinder head water jackets.
Before starting the engine for the first time, pre-lube the valve train by running the engine with the fuel shut off until oil pressure registers on the gauge. This prevents dry start damage to the valve guides and camshaft.
Many mechanics spray copper gasket sealer on head gaskets. Do not do this with MLS gaskets, as it can prevent the gasket from sealing properly. Always follow the gasket manufacturer’s installation instructions.
