These High Energy Die Cast Aluminum Roller Rocker Arms for Chevy V8 265-400 applications are perfect for street and moderate race use. With a 3/8″ stud diameter and 1.5 ratio, the die cast, larger-than-stock body of the rocker arms is made of aluminum for superior strength with light overall weight. High Energy Die Cast Aluminum Roller Rocker Arms from COMP Cams are an affordable option that feature a die cast, aluminum body with a needle bearing fulcrum and roller tip. Designed to be stiffer and more durable, these cost effective rocker arms are capable of providing added valve lift while withstanding the rigors of a performance application. Their specially engineered fulcrum and roller tip create far less friction than sliding factory models to lower oil temperatures, thus improving both response and horsepower. Snap rings are used to hold the trunion and bearings locked in place..

Product Features:

• Cost effective aluminum construction provides superior strength to weight ratio
• Needle bearing fulcrum and roller tip reduce friction and lower oil temperatures for improved response and horsepower
• Durable design increases valve lift while withstanding the rigors of moderate race use

VALVE SEALS, O-RING 11/32″ 1 ST

COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:

• Work with stock guides and 11/32″ valve stem diameter
• Valve stem oil seals keep unwanted oil from entering the combustion chamber
• Several different types of valve seals are offered

With Mr. Gasket cam degree bushings you fine tune the camshaft timing of your engine to as little as 1 degree. Even aftermarket timing sets with multiple keyways can’t give the range of adjustment these bushings allow.

Product Features:

• Advance the cam for increased torque and horsepower
• Tune your powerband for more end torque or increase top end horsepower
• Includes (4) offset bushings and (1) 0 degree bushing
• Cam sprocket dowel pin hole must be drilled to .406¿ (13/32¿) dia.
• Cam sprocket dowel pin hole must be drilled to .406┐ (13/32┐) dia.
• Increase Top-End Horsepower
