Cometic Chevy Gen-I Small Block V8 .040in MLS Cylinder Head Gasket - 4.165in Bores

When you're rebuilding the top end of your Chevrolet Gen-I Small Block V8, a reliable cylinder head gasket is crucial. This Cometic gasket is designed for engines with .040 inch overbore and 4.165 inch bore diameter, and it's made without steam holes, fitting 18/23 degree heads. It's a multi-layer steel (MLS) gasket, which is a popular choice for its durability and ability to handle the stresses of engine operation.

The construction here includes embossed outer layers that are coated with Viton, a material known for its resistance to heat and oil. Cometic also uses HP shim technology, which increases the clamping force around the combustion chamber. This is particularly helpful for open deck blocks, as it helps to improve the sealability and prevent leaks under pressure. This gasket is built to provide a solid seal for your engine's performance.
