About this part

Product Details

When you're rebuilding the top end of your GM Gen-V or VI Big Block V8, getting the cylinder head gaskets seated correctly is crucial for a leak-free seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring your rebuild stays solid.

Cometic uses multiple layers of stainless steel for these gaskets, which gives them increased strength and the ability to rebound, helping them resist corrosion and maintain a strong seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction means you don't need any extra sealants; the gasket is ready to go right out of the box, whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The center layer is stainless steel, and its thickness can be varied to meet different requirements, with this specific gasket set to a compressed thickness of 0.036 inches and a bore size of 4.540 inches.

This gasket is a solid option for a wide range of GM trucks and vans from the early to mid-90s, including popular models like the Chevrolet C1500 and GMC K2500. It's designed to fit right and perform reliably in demanding applications.
