Hyd Roller vs Hyd Flat tappet on SM heads

.040 is good, but .030 is better

Evidently its impossible with .600 lift. That's my point. The OP needs to correct his geometry because the sweep is so wide. But some others say it's impossible with .600 lift to get the sweep down to .040.

It's cRaZy to not try and help someone but **** like this make it about not worth it.
