Shaft mounted rockers

I just bolted on a set of Comp, had to enlarge the pushrod holes in the head because I am running a .600 lift cam. The rockers are a bolt on with stock OD springs. Also had to buy valve cover spacers. They dont fit real good, had to grind on them. It is never easy, but my experience has been that it is worth it because valve train is probably the weakest link in a pushrod motor. Buy the best rockers, pay the price, set them up right and you should never have a problem.

1) The pushrod holes definitely need elongation and a word of warning - be careful to not poke through the intake wall.
2) The inside rail of the head, where the pushrod end of the rocker rotates, needs to checked and clearenced appropriately
3) Pushrod length can be as short as 7.050 (as short as we have seen) so watch for that.
