I just bought a set of ETP LS7 250cc heads, and i am building a 468 cu in LSX tall deck motor and will use a Wilson nitrous cross plate w/ a carb, i heard these heads dont flow to well on the exhaust side, so if i have my engine builder do some more port work on both the intake and exhaust ports do you guys think that would be a good move or should i leave them alone and sell them??? Is 750-850 hp on motor unreasonable for this setup, i will be using a huge solid roller with alot of compression...
