Product Details
Cometic Gasket is known for making well-built engine sealing components. This Multi-Layer Steel (MLS) head gasket is built for Pontiac 326, 389, and 421 V8 engines, fitting a range of vehicles like the Bonneville, Catalina, and GTO from the late 50s to mid-60s.
This gasket uses HP shim technology, which is designed to increase the clamping force around the combustion chamber. This is especially helpful for open deck block designs, helping to ensure a strong seal. It's coated on both sides with Viton, a material that holds up well to heat and fluids, contributing to a reliable seal.
With a bore size of 4.300 inches and a thickness of .098 inches, this gasket is a solid option for rebuilding or repairing the top end of these classic Pontiac V8s.
