These are race heads... I bought them from Davescuda a few weeks ago.
.700+ ?? really ? I was thinking 600ish... but plan on having the cam custom ground so we will see whats recommended.
You may have trouble getting that much lift with solids but a roller is no problem.
If they want less than a .700 net lift they'd have to explain why, and it better not be the heads don't flow any more up that high. Those heads will easily take that much lift. But the geometry has to be right. I net .600 on Pcar heads. If it was a race engine I'd say you need to net closer to .775 but that is hard to do without moving the shafts more than they can be moved.
