Cometic Chevy Gen1 Small Block V8 .032in MLS Cylinder Head Gasket - 4.200in Bore - 18/23 Degree Head

If you're rebuilding a Chevrolet Gen-1 Small Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for ensuring a proper seal. It's designed for a 4.200 inch bore and features an 18/23 degree head angle, with round bores and steam holes. This gasket is built to handle the demands of higher output engines, making it suitable for a wide range of vehicles from the 1980s and early 90s, including models like the Chevrolet Camaro, Corvette, and GMC C1500.

What makes this gasket stand out is its construction. It's made from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This advanced construction means you don't need to use any additional sealants, and it works well with both aluminum and cast iron blocks.

The compressed operating thickness of this gasket is 0.036 inches, with an initial thickness of 0.032 inches. This precise sizing is important for maintaining proper compression ratios and valve-to-piston clearance, especially when working with performance builds.
