Description
A quality head gasket is non-negotiable when building or rebuilding a performance LS engine—it’s the critical seal between your cylinder head and block that determines whether your engine holds together under boost or extreme combustion pressures. The Fel-Pro 4.100 MLS Head Gasket is engineered with multi-layered steel and KEVLAR fiber construction to reliably contain pressures up to 3,000 psi, making it the trusted choice for builds pushing toward 1,000 hp. The anti-stick coating and pre-flattened copper rings mean you get a proper seal on installation and won’t fight removal when you need to service the engine down the road.
