Don't think they made a big difference as far as power but it could be because
the TB is to small now. But the stock heads started pushing water at 14lbs so it was either fix the old or buy new. And I don't think price wise after having the old heads fixed and ported was much different than just getting TF heads. And I did bump up in CI plus went with a larger cam and it only made 50 more horse. So hard to tell but I can tell you it wants a whole lot more air.
