Alignment with ductile-iron rockers?

Valve train geometry is very important.

Really?? Nobody told me! (/s)

I am only inquiring as to this particular aspect of geometry with these specific rockers. Given that the pad is designed to slide on the valve tip, my theory is that side-to-side alignment is not critical. As mentioned above, as long as the pad stays on the valve tip of course.

Anyway I'll center them "just because" even if it's not mechanically required...
