As long as those heads were ported well, and have bigger valves, you should be at 300 hp. Make sure you get it tuned too. Other wise you will be dissappointed. Many go with the LT4 hot cam. That cam is a love hate cam. You either love it or hate it. Othe popular cams are the CC306 (230/236), Or a 224/230 cam.

You might want to go with a 52mm Throttle Body instead. 58mm TBs are made for monster engines. In fact, a 58 could actually hurt power if you don't have a combo that can utilize the extra air flow of the 58.
