my buddy and me built a 383 for his s10. i dont remember all the specs but we used what we had for heads. their dart pro 1 230's with 2.08-1.60 valves. 64 cc chambers.the comp ratio is 11.1-1. i got a feelin we are usin more head than we need. what if any is the down side to havin too much head on this engine?
