# Cometic Pontiac 428/455 V8 .051in MLS Cylinder Head Gasket - 4.380in Bore - No Water Holes

The HP shim technology increases clampload around the combustion chamber, thereby increasing the sealability of the head gasket around the open deck block.

-   The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
-   The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements
-   Requires less clamp load creating less bore distortion
-   Conforms load distribution across the sealing area
-   Embossed Outer Layers Coated w/Viton
