Brand new set of 8 x 3/8" Pontiac V8 Head guide plates for the Pontiac V8.
C.A.T Chrome molly steel guide plates are manufactured from cool rolled 5140 chrom moly steel plate.
This is a set as needed for one engine... 350,400, 455.
These hardened steel guideplates keep your pushrods in line with your lifter cups and rocker arms, and prevent deflecting, or walking sideways.
