Looking to see if anybody might have some insight on an issue I have with my 71 340 engine that I had a stock rebuild with just a little more than mild cam. I just sent engine to be put on an engine run stand to break in before installing in car. The shop told me the push rods are rubbing the stock J head holes. The rocker set ups are stock ( all rockers together on rail shaft) .I'm just checking if anybody has experienced this issue. Are left and right rocker assembly's Thanks in Advance!
