Max horsepower with EQ heads?

Some guesses on my part on a full on bracket build; Use EQ heads ported. With 2.08/ 1.60 valves. 408 cubes.
Depending on if the valvetrain can be made (at a reasonable cost!) To tolerate a solid roller with enough duration to run 7,200 rpm, I would try a cam of about 270/284/110 @ .050 to compliment the 14/1 compression i would shoot for. My choice of lsa is based off Vizards chart, which predicts a 107 with high compression, then add 3 degrees lsa to compensate for the 14 extra degrees exhaust duration to keep the same overlap as a single pattern 270 @ .050 cam. A tunnelram with a pair of 750s on top, or in my case, since i already have a system, a hat injector on methanol. Stepped headers ( 13\4 to 1 7/8?). Run a 6200 stall converter for starters, shift at 7,000.
My guess is a motor like this will make 650 plus hp. Comparing it to RAMM's 417 build,The cam may move the torque peak up 1,000 rpm? Compression ought to be worth a 4 percent power increase, the tunnelram ought to make 30 hp more than a single four.
In my 65 Dart drag car it would weigh about 2980 with me in it, and if my power prediction is close, it would run 9.80 to 9.90. I would have to short shift it to leave the fire suit at home!
