The small block Trick Flows (aluminum) are supposed to be the best out right now. I believe they are completely bot on, except possibly the pushrods, which may need to be a 1/4" longer? I reference this from the Mopar Action magazine; they put a set on a small block build and I remember them saying they needed longer push rods. I am planning on putting a set on my small block too, but that won't be for quite some time.

2nd link is for head w/ 10 degree locks and larger springs. There are a few options you can choose from.
