Dyno numbers are only numbers. I've rarely seen dyno numbers equivalent to the same numbers on the drag strip. The e-heads have decades behind them and because of that there are far more racers with e-heads on there cars. As for one off billet heads except for the Visner all the other heads can be bought in cast form. Speed cost money, most Pontiac racers are cheap, only few are willing to set it out (money & time), the ones that do are rewarded. Butler , KRE, Cooper, Welter, Justin, etc. all have a lot in common.....not enough time or money.......no MEGA company's here! You wanna go fast how much time & money you got......it's pretty simple. E head can't compare to the Warp 6. Visners CV head, DCI RA5 head are two heads with more time on them WILL easily surpass the e heads.
My engine runs on alcohol.....what ifs are silly! I'll run any car with any head, anytime....same boost, same weight....same day....same strip with my HP heads. I'll be at Norwalk.
