If you had to chose, which heads would you go with? I have basically no mods right now. Should I start with a different mod?

I was looking at the PPI domes... they offer 180 psi and 200 psi domes. Which would be better for this setup. And I know i have to run premium race fuel to run these.

Send your head to Harry Klemm at groupK and have him mill the head for premimum pump fuel. The last thing you need is a race fuel head on that motor.

how much $$ would that run, and how much could i really get out of it?

Probably under $100 and you would get the same results as buying a new aftermarket head. The real savings will come when you do not burn up your motor.
