Fits 1965-2000 Chevrolet 396-572 Mark IV/V/VI Big Block
Part Number: 5863
These are high quality gaskets that works well on those hard to seal applications. The low density fiber & rubber blend gasket material seals those minor head imperfections with a low clamp force. At .3125 inch, the extra thickness can also offer slightly more clearance for roller rockers. Ideal for all those high performance applications where you take the valve covers off and on a lot, and sticking is a problem.

Features and Benefits
• Ultra Seal Cork and Rubber Blend
• Extra Thick 5/16 (0.3125) In creates positive seal and provides additional clearance if needed
• Also Available In Standard Thickness
• For OE Replacement And High Performance Apps
