Ported head and bigger valves

What is the total advance, and at what rpm is it "all in"? Keeping track of what idles/responds best at what initial adv., and what total adv gives the best hp w/o detonation is key, You can tailor the total mech. with an FBO plate set-up or similar technique. Tube headers,..dramatic mod to make along with that head,....both good ones....
