Are Stock ls6 heads limited on performance? I'm wondering can i go in the 10's with this stock head's and aftermarket cam. Im going to run 3.73 gears, 125 wet shot, and LT headers ,ory and Lid. With a good tune. What cam works great with these heads I want to make good hp on motor but really go in the numbers with nitrous. If I can run 10.90's or better im good. O yea I will be running a 3600 stall.
