These heads are AFR 225’s 72cc worked by Cartek , heads are complete with 2.055/1.60 valves , inconel exhaust valves , bronze guides , 921 springs .
These are the same heads/cam that Mike Romain ran on my his big bore 388cid single turbo set up that ran 9.33 at 149, the heads are ideal for a 4.125/4.130 bore . I bought these, had new guides and a complete refersh (done by Bakers Cylinder Heads in Henderson NV - over a thosand dollars additional invested). I paid A LOT for these heads …and as the story goes, my loss - your gain. I have the cam that was part of this combo for sale as well.
