Description
These hardened guide plates will allow for the correct rocker arm geometry when using a true roller rocker on an iron head application. They are significantly thinner than your basic guide plate, allowing for the rocker arm to sit lower without interference with the rocker arms stud. A must have if you are using an iron head with roller rocker arms. Application 7/16th stud with a 3/8ths pushrod. Note: To utilize a 3/8ths pushrod in an Oldsmobile iron head, the 16 pushrod holes need to be modified for clearance.
