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...

hi i was wondering what machining would have to be done if i get a 331 stroker kit. i was wondering how much machining would cost. would i have to change cam? :headscratch:
