Proform 141-103 - Officially Licensed GM Valve Covers for Small Block V8

These chrome valve covers are made of heavy-gauge steel for small block V8s. In most cases, these covers are at least 20% thicker than typical aftermarket covers to prevent leakage around the valve cover flange area typically caused by over-torqued fasteners. The valve covers bear the Chevrolet and Bow Tie logos. Oil-restricting baffles are offered in some covers for those who want to maintain the PCV hookup.
