About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is what you get when you need a solid seal for your GM LT1 or LT4 Gen-2 Small Block V8 engine. It's built with multiple layers of stainless steel, giving it the strength to handle high-output applications. This gasket is designed for a 4.100 inch bore and has a compressed thickness of 0.045 inches, making it a good choice for many rebuilds and performance builds on vehicles like the Chevrolet Corvette, Camaro, or Pontiac Firebird.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments up to 482 degrees Fahrenheit. This coating means you don't need to use any extra sealants, and it works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The multiple stainless steel layers not only add strength but also help the gasket rebound and resist corrosion, ensuring a reliable seal over time.
