VALVE COVER ADAPTOR Chevrolet 409 348 Valve Cover on 1959-86 Small Block Chevy

Chevrolet 409, 348 Valve Covers. On 1959-86 Small Block Chevrolet Head.

INCLUDES STAINLESS STEEL BOLTS AND WASHERS. (Head and Valve Cover not included just shown for display). We are a Manufacture of Billet Valve Cover Spacers and Adaptors. All of our Spacers and Adaptors are Made in USA with USA Made Materials. With Medice Manufacturing Valve Cover Spacers you no longer have to use tall valve covers to clear enhanced-performance valve train components.

Utilize your factory valve cover (or any valve cover) and gain space for high performance valve train parts/components. We also manufacture valve cover adaptors / conversion kits to put different valve covers on different engines. GASKET LOK feature incorporates a relief cut in critical areas.

This addition process causes the gasket material to become imbedded into the spacer providing a tighter grip of the gasket against the spacer surface. GASKET LOK is compatible will all premium gaskets on the market. The result is a better seal with greater gripping action to keep the gasket in place. Some information about installing our valve cover spacers.

IF you are using an aftermarket aluminum head with a good, machined valve cover surface many people (including myself) just silicone the spacer to the head. IF you are using a cast aluminum valve cover & it is good, flat & straight in the gasket surface then just use Silicone (form-a-gasket) between the spacer &valve cover. IF your Head is as cast and rough, we recommend using a gasket between the spacer and the head. IF you are using a tin valve cover (once again MUST be flat) I recommend a gasket between spacer & valve cover. MOST IMPORANT everything MUST be clean & MUST use a good quality gasket. The BEST silicone I have found is Ford Motorcraft RTV for use on 7.3 Power Stroke Diesel Engines! You can get it at your local Ford Dealer.
