    But thats just the thing, i see poeple pick up 15-20rwhp on a port on 241 heads, and i see people pick up 30-35rwhp on a 1500dollar set of heads. Sometimes 1500 for each head. I mean i want to learn how to get hp gain without having to buy 2000dollar heads. Im just gonna pratice on the supra, i know the heads are different but the general idea is the same and dyno run it without head work, then switch the head and run it again. It only takes me 3 hours to pull the motor on that car it shouldnt take to long for head swap. and well see if there is an improvement.

    NAPA Auto Parts does Valve jobs for $150 a pair you can't really go wrong with that deal, and if you want them ported and polished and a valve job they do the pair for $350 bucks thats a pretty good secret out there...
