Fel-Pro SBC MLS Head Gasket 4.165in Bore .040in 1143

A quality head gasket is fundamental to engine reliability and performance—it's the critical seal that prevents combustion pressure from escaping and coolant from leaking into the cylinders. The Fel-Pro SBC MLS Head Gasket is engineered specifically for Small Block Chevy applications and designed to handle the extreme pressures of high-performance builds up to 1,000 hp. If you're rebuilding or upgrading your engine, this gasket delivers the durability and sealing integrity your investment deserves.

Constructed with KEVLAR fiber reinforcement and multi-layered steel construction, this gasket withstands combustion pressures between 1,500–3,000 psi without compromise. The anti-stick coating ensures a perfect seal while remaining easy to remove during future rebuilds, and pre-flattened copper rings simplify installation. This is the gasket serious builders choose when reliability and performance matter.
