which heads?? I recently recieved the advice that .030 would be good. It would bump compression to 11 to 1 and give a noticeable increase in throttle response and give about a 4% power increase. That was advised with a tr224 with 564 lift so you should be fine with your cam. Also, this was using a stock thickness GM MLS gasket
