302 Boss, 351 C Modified 3/8 Guide Plates (Set of 8)

To convert Ford 351C engines to adjustable rocker arms and pushrod guide plates, machine the old rocker stanchions down to a height of
.550" as measured from the adjacent head bolt spot face with cutter 41860. Drill and tap the old screw hole to accept stud 42277.

With the use of high lift/high pressure springs, guide plates are a must in todays performance engines. Case hardened pushrods must be used.
