SBC MLS Head Gasket 4.100 Bore .026

The SBC MLS Head Gasket 4.100 Bore .026 from FEL-PRO is a precision-engineered gasket designed specifically for small-block Chevy engine builds requiring tight bore diameters and controlled compression heights. This multi-layer steel (MLS) gasket represents the modern standard for high-performance and street engine applications where reliability and consistent sealing are non-negotiable.

MLS head gaskets use multiple hardened steel layers sandwiched together to create superior sealing surfaces across combustion chambers, coolant passages, and oil galleries. The 4.100-inch bore dimension accommodates larger displacement or overbored small-block applications, while the .026-inch compressed thickness provides precise control over combustion chamber volume—critical for maintaining accurate compression ratios in modified engines.

This gasket is ideal for engine builders and mechanics installing aftermarket cylinder heads, increased displacement engines, or performance-oriented rebuilds on small-block Chevy engines. FEL-PRO's engineered design resists blowout, reduces gasket creep over thermal cycles, and eliminates the need for retorquing that plagued older composite gaskets.
