302 331 swap

  1. 5.0L Tech
    I have a 331 with aftermarket heads. I used the push rod lenth comp cams recommended and the rocker bottoms out on stud. Just wondering if what I am doing is wrong? I used a 1/2 inch longer pushrods than recommended and it seemed to fix the problem I quess. I've never had stud mount rockers...
