What a MLS Cylinder Head Gasket 84.5/.030″ does

A cylinder head or block gasket seals the joint between major engine castings so that combustion pressure, coolant and oil each stay in their own passages. The bore size and compressed thickness printed in the listing name matter: the bore should suit the bore of your block, and the thickness affects the compression ratio and the gap between the valves and pistons once the head is torqued down.

The Cometic C4241-030 is listed under part number C4241-030.
