All Cometic products are made in the United States with materials manufactured on American soil. Cometic MLS head gaskets are ideal for any combination of head and cylinder materials, making them a versatile choice for performance engine builds and rebuilds. Thicker versions are available to reduce compression and allow for correct piston-to-head clearance when pistons stick out of the block.
