Engine Assembly Basics -- Cam, Valvetrain, Top-End Photo Gallery
The cylinder head gaskets are an important part of the assembly. The gaskets must be capable of sealing at the power and pressure levels the engine will encounter, and be of the correct configuration for the engine. The gasket's thickness should provide the desired piston-to-head clearance, particularly when setting the engine up for a useful quench effect. These Cometics for a big-bore 572 Mopar were custom ordered for the bore size, and give 0.040-inch clearance to the narrow quench band of the custom dished pistons.
