Hey guys, I'm doing a swap in my 79 f-150 from a 400 to a 460 but I've see other people have clearance problems with running tall valve cover for full roller rocker systems. Comp cams has a roller tip rocker that I'm looking at going with but they say they clear most stock valve covers. Does anyone know what the height of a stock valve cover is?

 

i have scorpion rollers on my 460
and factory valve covers clear them.

 

My factory cover clears my CompCams roller tip rockers just fine.

 

I have harland sharp full rollers on my 429 and they clear stock valve covers. I put a set of tall valve covers on my race car and they are tall. There would be serious brake booster problems if the master cylender was not under the floor. I bought the comp cams roller tips for my fe motor and they were crap. the pocket for the pushrod cup did not have enough clearence and would pinch the pushrod, it accually broke my pushrods. You may have no problem but watch out for clearence problems.
