I was wondering if anyone is running 781 heads and how much lift do you have? I'm looking at a set right now and wondering how much lift they can handle. The cam i wanna get is .544/.564 lift and 226/234 duration. :confused:

That's what i was thinking as well. Gonna do a port job on them, grind the valves and seats. Then maybe get some stiffer springs as well.
