Fel-Pro SBF MLS Head Gasket 4.100in Bore .041in 1133

When you're building or rebuilding a high-performance Small Block Ford engine, your head gasket is the critical barrier between combustion chamber pressures and catastrophic failure. The Fel-Pro SBF MLS Head Gasket is engineered specifically for forced-induction and nitrous applications, delivering reliable sealing even under extreme cylinder pressures that would compromise lesser gaskets. If you're chasing serious power numbers, this is the gasket that won't let you down.

Fel-Pro's multi-layered steel construction with KEVLAR fiber reinforcement is designed to withstand combustion pressures between 1,500–3,000 psi, making it suitable for engines producing up to 1,000 hp. The anti-stick coating ensures a perfect seal while allowing clean removal during future rebuilds, and pre-flattened copper and steel rings simplify installation on your engine block.
