I just installed screw-in studs and guide plates. I put the pushrods back in and the rockers, but now the rockers don't sit square over the valves. The tops are kicked outward on both intake and exhaust. I checked the part numbers and everything matches up how it should. I have 5/16 X .08 pushrods and guideplates for 5/16" rods... I'm lost as to how this happened, its got to be a simple thing??
