I cannot do that, I have already sent the rockers back to where I bought them and put my old ones back on. From what I have learned through this process the shaft will need to move up and toward the intake to get to ideal geometry. Once I learned I would have to likely pull the heads to make these work I just went back to what I had, its too close to race season to be messing around things like this. I would have been willing to employ bolt on solutions that don't require removing and cutting on the heads. I appreciate the help very much.
