COVER-VALVE-BIG BLOCK-POLISHED SAND CAST ALUMINUM-TALL-PAIR-65-74 (#E20909)

1965-1974 CORVETTE POLISHED ALUMINUM TALL VALVE COVERS - PAIR.

These valve covers are a bit taller than stock to fit over many roller rockers, such as Jesel. Using double gaskets to add height frequently causes leaks. Customers have reported to us that PML tall valve covers eliminated the need for double gaskets and the leaks.

These big block engine C2 & C3 Corvette covers do not have a brake booster cut-out on the driver's side in response to customer requests.

Engine configurations vary so please check for clearance for larger valve covers. The walls and gasket flange are thicker than stock and the fins and script add height to the top.

Look for clearance on the inside also, especially if you have roller rockers. A simple check can be made if you have the stock valve cover. Set the stock cover on the head and measure the distance, if any, between the gasket flange surface and the head. Our cover is approximately 3/8 to 1/2 inch taller than the stock cover. PML tall covers are approximately 3/8 inch taller than our standard height covers.

Some customers have reported that their roller rockers contact the inside of these PML valve covers at corners. PML has heard that grinding a bit off the roller rockers on #1 intake and #6 intake, one intake rocker on each side of engine, can add enough clearance (but this is not something we have tried or endorse).
