Highest flowing sbm heads?

That build, Brett ported the head IIRC. That’s really the biggest key in making power, a high flow head. While that Victor head and the higher performing W’s are worth it for the up most power potential, the common man will not afford these in his build.

For the most part, people want a OOTB ace head to bolt on and go. (Save a check out at your machinist if you yourself can not perform this task properly) I don’t think this is currently possible. At least at the above engines power level.

I don’t have it in my head what the cost difference would be between a RPM head and the Victor, attaching parts included, even more so if you go with a solid roller. But that’s the entrance fee.

Also! A OOTB head will go only so far before porting, hence what’s the highest flowing head question. How far does anyone think a Victor head can go untouched? On a general rebuilt block?

I think what you would get would be a poor showing next to the engine above but still, even if you produced an engine 130hp less, your still looking at a 600hp small block.
