These aren't just bare castings; they are a pair of new, complete cylinder heads from DK Engine Parts, meticulously pre-assembled with a full valve train.

- Complete Assembly: Each head is fully loaded with a new valve train, including valves, springs, retainers, and other essential internal components, eliminating the need for costly and time-consuming assembly.
- Critical Engine Sealing: When bolted to the engine block with a head gasket, the cylinder head creates the necessary tight seal to contain explosive combustion pressure, which is vital for proper engine function.
- Optimized Performance: The pre-assembled valve train precisely controls the flow of air, fuel, and exhaust into and out of the cylinders, a key factor in maximizing engine reliability and performance.
- Ready for Upgrade: These heads serve as an ideal base for a high-performance engine build and are designed to work seamlessly with aftermarket components like high-strength head studs and gaskets.
