(8) Adjustable Guide Plates: Big Block Chevy; 3/8" Pushrods

The innovative new guide plate design from COMP Cams¨ compensates for the Chevrolet Big Block's splayed intake and exhaust valves, which are tilted in two axis. Perfect for use with aftermarket cylinder heads, rocker arms and pushrods, these adjustable guide plates eliminate misaligned rocker arms and valve stem tips. A single fastener quickly locks the two halves of the guide plate together. And, if valve train parts are swapped, the guide plates can be easily readjusted to fit the new setup. They are available in sets of eight for 3/8" diameter pushrods. Precision die-stamped from premium heat-treated steel material, the COMP Cams¨ Two-Piece Adjustable Guide Plates are the quickest and most accurate way to align valve train components in Big Block Chevy engines. These performance guide plates work with all RHS¨ cylinder heads, as well as other popular performance aftermarket cylinder heads that feature relocated intake ports.
