Depends on the budget but most will say AI or TEA for stock castings (AI uses stock valves)...PRC LS6 2.5 is good choice as well for little less $$$. AI and TEA have been proven to perform on par with aftermarket castings on N/A builds. TFS, PRC or AFR for aftermarket will all perform exceptionally well. TFS needs full roller rockers, AFR and PRC can use stock rockers. For a blown application aftermarket heads have thicker decks to help contain the added pressure of forced induction. As for power , they will all make great power but reliability might favor the aftermarket castings a little depending on how much boost you plan to run.

The factors that are crucial N/A are not as critical when running boost ,such as intake runner CC, PTV for large cams and milling for higher compression. If you have a blower cam already, aren't going to really pump the boost higher and want a nice 30hp gain at least for a good price I would say PRC 2.5 LS6 64cc or 6.0L with 72cc for less comp and more boost. They have the same runner profile and flow 316 cfm which is about 50-60 more than stock LS6's. Plus you can sell your heads and offset the cost even more.
