Review on 🔧 COMP Cams 4808-8 Guide Plate for 5/16 Diameter Pushrods, Black - Small Block Chevy Flat by Mike Sutton

I upgraded my 1990 Corvette with factory heads to standard tappet guides and rocker arms and in this kit my roller tips are not perfectly aligned. If I move the rocker arm to the side, I'm sure it moves far enough for the rocker arm body to touch the valve tip. So for me it's a waste of money and I buy adjustable baffles. I have a factory aluminum head AKA 113. This is my experience with this casting, but other castings may work.
