Cometic GM SB2.2 Small Block V8 .040in MLS Cylinder Head Gasket - 4.150in Bore - With Steam 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
