4.200 MLS Head Gasket .027 - SBC

The 4.200 MLS Head Gasket .027 - SBC from Cometic Gaskets is a precision-engineered sealing component designed for small-block Chevy engines requiring reliable head-to-block compression integrity. This multi-layer steel gasket serves engine builders, mechanics, and performance enthusiasts who demand consistent bore sealing across rebuild cycles and street applications.

The .027-inch compressed thickness is critical for maintaining proper combustion chamber volume and valve train geometry. Cometic's multi-layer steel (MLS) construction utilizes stainless steel facings and elastomer core layers to distribute clamping load evenly across the gasket surface, enhancing durability and longevity.

Technicians rebuilding carbureted, fuel-injected, or forced-induction small-block engines will find this gasket particularly beneficial, as it excels under thermal cycling and vibration, making it suitable for both stock and aftermarket head castings.
