I could see 13:1 and a good induction system with the appropriate roller doing 600. But I doubt it will do it at 6k. I think 7 should be the bottom, and 7500 would be better.
^^^ Agree.
I hope they make an offset intake rocker version of this head that comes in at 220ish cc with a 2.055 - 2.08 valve. Would really let a lot of these street stroker builds hit that magical 600 mark.
