roller rockers
I just think it is something guys are doing because they like the extra work I guess. You can pick-up more lift (maybe) an average of .030". I don't see too many guys doing this now days. You could end up realizing you were better off w/ what you had before changing 8 rockers. IMO, some of them do it because its easier than changing the cam maybe to run nitrous. Just a thought
If it were easy, EVERYBODY would be doing it!!!!
