Fel-Pro 1075-041 is a PermaTorque MLS head gasket for Chevy Big Block V8 engines, built to help seal high-pressure combustion chambers when real-world block and head surfaces are not perfect. Its multi-layer steel construction, targeted sealing beads, and blue aftermarket coating support demanding street, strip, and performance rebuilds on 396, 402, 427, 454, 502, 510, 540, and 572 CID Big Block Chevy applications across Gen IV, Gen V, and Gen VI engine families.

Fel-Pro 1075-041 Technical Specifications:

• MLS construction uses multiple steel layers to maintain clamp load and combustion sealing under the casting movement common in performance engines.
• Multi-layered steel bore bead combustion seal is designed to concentrate sealing force around each cylinder opening.
• Advanced polymer coatings help the gasket conform to a wider range of surface finishes found during engine repair and rebuild work.
• Bore diameter measures 4.580 in. or 116.332 mm, with a compressed thickness of .041 in. for precise engine assembly planning.
• Compressed volume is 11.200 cc, giving engine builders a known gasket volume for compression ratio calculations.
• Engineered as a direct-fit replacement for Chevy Big Block Gen IV, Gen V, and Gen VI V8 platforms with 396, 402, 427, 454, 502, 510, 540, and 572 CID displacements.
• Built to exceed OE specifications and validated for fit, form, and function in the intended Big Block Chevy applications.

Includes:

• One head gasket.
