Guideplate HELP!!! November 12, 2007, 02:33:23 AM I added guideplates to my GT40-P heads and the rocker arms do not line up with the valves anymore. Is this due to the change in design to this head? I.E. Valve location, plug angle? I am extremely puzzled, OH and where do I get specific guideplates for GT-40P heads to fix this problem, The pedastels have been milled off so I now must use this set-up. WTF I thought that COMP Cams would have noticed this and had a seperate guide plate. Can I use a chop saw to widen the grove or just buy a set of guide plates for a 3/8" push rod and that will fix the problem? Has anyone had this issue before? Quote Selected
