Chevy Sm Block COMETIC 4.165" Bore
The GM Gen I Small Block V8 MLS Head Gasket features a 4.165 valve pocketed bore.
It is comprised of multiple layers of embossed stainless steel, with the outer layers utilizing a Viton rubber coating.
The compressed operating thickness measures .036.
Steam holes are included.
Each COMETIC MLS (Multi-Layer Steel) Head Gasket provides maximum sealing performance for high output engines and requires no sealants.
MLS gaskets are suitable for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks.
They can withstand the shearing force created by the two materials.
Increased strength is achieved due to the multiple layers of stainless steel, which also allows for rebound and corrosion resistance.
The outer layers are embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material that is heat resistant to 250 C/482 F.
Viton meets the demands of various harsh sealing environments, load conditions, and surface finishes.
The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.
