Since the valves are spaced further apart, the rockers also need to be properly spaced so the alignment is correct. You should be able to make the corrections to the HS rockers, or some owners have sent them back to the manufacturer to have this done.

I can't see how the rollers can be centered on the valve stems by spacing. The pushrod needs to be offset like the T&D's. Also, I have large springs that the HS's hit.
