Pushrod problem with Speedmaster heads

@B3RE

Maybe Mike @ b3 can help, he is the man on valvetrain geometry

Mike and his kits are awesome. In my case the correction kit caused this issue to become worse. Not B3's issue or problem, its just where the Comp rocker lined up with my valve tips to get the geometry correct. Its just the way it goes. A different set of rockers (Hughes) lined up better than the Comps with no correction, and got rid of my push rod clearance issue (FYI we did open up the ends of my heads to help but it wasn't enough). High lobe lifts and/or lifters with taller push rod cups (i.e. roller lifters) will exasperate the problem by shortening the push rod and angling the push rod even more and you actually loose lift.

If you've ever assembled an engine with canted valves you can see this in a more dramatic way, but most of those use studs and you can move the rocker with a longer or shorter push rod to correct the geometry some (I say "some" because no two brands of rocker pivot to roller to push rod cup are the same) where as with shaft mount and cast pedestals, you can't unless raising the shafts helps the geometry in some cases.
