We are working on our version of Indy's TA heads, fully cnc ported, 5/16 valves, 3-4 spring options, and should flow around 315cfm at .650-.700 lift.
This is the old IndyBrock head but we'll be using a hybrid PRW stainless kit for everything except solid roller and then we'll use TD hybrid kit.
The pushrod pinch is moved over quite a bit and should allow more rpm and higher rpm power on any engine they're used on. They'll only have 2.08 x 1.60 5/16 valves, and only a max cnc ported port for now...mainly to give guys with large cid small blocks a good 600+HP cylinder head without a ton of $$$.
I won't have anything concrete until Feb. but I will stock them once we evaluate them on a couple of different engines.
