Well I dont know how insane those heads are, but YOUR POWER IS IN YOUR HEADS.I would have them 5 axis fully port&pollished with a major rework done to hold even larger valves, open up the itake runners, and free up the exhaust side a bit too. If I am right, I believe those heads only flow in the area of 220 CFM @ .600 on the intake.Now all that is pretty expencive, but you will pay it if you cant hit 10s with your current setup LOL.Anyways I am not sure about what else you have, but try an electric water pump, will save you alot in high RPMs.BTW you have a stock crank in there????Can a stock crank hold up to 7000-7500 RPM runs?Thanks.
