Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is built with a .070 inch thickness and a 4.300 inch bore, making it a solid option for your Pontiac 326, 389, or 421 V8 engine rebuild. The advanced HP shim technology integrated into this gasket is designed to increase clamping force around the combustion chamber. This is particularly beneficial for open deck block designs, helping to ensure a strong seal and prevent leaks under pressure.
The gasket is coated on both sides with Viton, a high-performance fluoroelastomer known for its resistance to heat and oil. This coating further enhances the gasket's ability to seal effectively and withstand the harsh conditions within the engine. This gasket fits a range of classic Pontiac models, including the Bonneville, Catalina, and GTO from the late 1950s through the mid-1960s.
