    What kinda gains should I expect from my ported 241's

    Dropped my heads off to Tom01SS (not sure if hes here) for a full port. He does Bare Essentials Racings work. Mostly on the Vette forums....anyway im mating this up w/ a G5x2 cam. Probably going to get her tuned locally @ ECS..Guys w/ similar setups what kinda power should I see from the heads and from both?

    I never had my car on a dyno, but the butt dyno showed noticable gains when I ported my 241s. At the same time, after I ported them I had a valve job done and the heads milled down to give me 57 cc chambers...engine had a lot more pep and very responsive.
