Product Details
These COMP Cams adjustable guide plates are made from hardened steel with a black oxide finish, giving them solid durability for your engine build. They're a two-piece, flat design intended for use with 3/8-inch diameter pushrods and 7/16-inch rocker studs. This set is specifically engineered for cylinder heads that have relocated intake ports, ensuring proper clearance around head bolts and a precise fit.
The stereo lithography techniques used in their creation mean an accurate fit right out of the box. Once you've made your final adjustments for valve train geometry, these guide plates are even able to be welded in place for a permanent setup. They are designed to work with Chevrolet 265-400 c.i.d. Small Block engines and Ford 289-351W engines.
