Cometic Chevy Gen-1 Small Block V8 .066in MLS Cylinder Head Gasket - 4.125in Bore

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, getting the cylinder head gaskets right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, offering a reliable seal without needing extra sealants.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel, and its thickness can be varied to meet different requirements; this particular gasket has a compressed thickness of .066 inches and a 4.125-inch bore, making it suitable for a range of Gen-1 Small Block V8 applications, including many Chevrolet, GMC, Buick, and Avanti models from the early to mid-80s.

It's designed to work well with both aluminum and cast iron blocks and heads, and it can handle the shearing forces that can occur when different metals are used together. This gasket also features valve pocketed bores and steam holes for proper engine function.
