Cometic Chrysler 392 FirePower .030in MLS Cylinder Head Gasket - 4.100in Bore

If you're rebuilding the top end of a classic Chrysler 392 FirePower engine or a modern Ram truck, a solid head gasket is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, offering a reliable seal without needing extra sealants. It's designed to work well with various block and head material combinations, including aluminum heads on cast iron blocks, and can withstand the forces created by dissimilar metals.

This gasket features multiple layers of stainless steel for increased strength and rebound resistance, which also helps prevent corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. The center layer is stainless steel and can be varied in thickness; in this case, it's set to achieve a compressed operating thickness of 0.036 inches, and the bore size is 4.100 inches, with the gasket being 0.030 inches undersize. This construction makes it a well-built choice for engines that push the limits.

This gasket fits a range of vehicles, including classic Chrysler models from the late 1950s and modern Ram trucks. Always refer to your vehicle's specific service manual for installation procedures and torque specifications.
