Description

Through innovative engineering, PROFORM has developed a valve cover that will take your generic looking stock LS engine, and give it a totally personalized look. These new valve covers are taller than stock valve covers, and can accommodate a wide variety of large valve train applications. These valve covers are available in multiple styles, which include raised and recessed emblems. Unique mounting studs, and oil restricting baffles are included. Threaded mounting holes for the optional Integrated Ignition Coil Bracket included. The passenger side valve cover has an oil filler hole. Officially Licensed Chevrolet Performance Parts Product. Sold in pairs. U.S. Pat. D657,798.

The following rocker configurations will require the valve cover to be slightly modified. Jesel part numbers: 317070, 317575, and 318080. These valve covers will fit LSX-DR heads and clear the shaft mounted valve train. The mounting bolts included with these LS covers are not compatible with the LSX-DR cylinder heads.
