Not sure if I’m at the right place to be asking tech question. First time on this site. Rebuilding 302; get it broke down and find it has roller cam and roller lifters but it’s been running with flat tappet rockers. It’s got me scratching my head. I thought if it had rollers it would have to have roller rockers. Am I missing something here. (It’s an 85 mustang 302). My first on my own rebuild. Only have worked on flat tappet cams, lifters & rockers. The guy I bought it from said it was all...
