Best: PRC 215's (aftermarket casting).
Good: PRC Stage 1 LS6's (Ported GM casting).
While the ported GM castings are a nice way to go, and they are definitely easier on your pocket book, the aftermarket castings offer some nice advantages over them. The laid over valve angle of the 215's gives you some additional piston to valve clearance, while still getting you the extra airflow from the larger valve size. Also, the 215's have a thicker deck surface that will grow with you into new combos, particularly big power adders, down the road.

The Stage 1 LS6's are the only ones of that casting that will clear without flycutting. Stage 2's or 3's you'd definitely have to cut reliefs!
