Not your budget, I know but,...take it from a douchebag thats spent alot of money, more then once, on the same products.... then ended up buying what I really wanted in the end.
Any of the heads you mentioned would work but, the 205's would rock that setup of yours pretty well.

V-series has some for sale. Budget heads are your "as-cast" heads that are ported. A good majority use the PRC 2.5 LS6 heads. They are in the $1500. With those heads, you get a .5 compression bump. You would end up with a 25-30 whp increase with those heads. Your higher dollar heads : AFR, TFS, will net you quite a bit more than the as-cast selections. Not to mention, AFR 205's are emissions legal if that is a factor.
