Heads for 440

looking like im not going to do anything with the engine. The trick flows along with all the other things needed to make them work are just out of my price range. I just dont think the CNC stealths would be worth messing with as the flows even after the cnc porting isnt near what the TF's are out of the box, plus it looks like i need the smaller chamber of the TF's for some quench that i have none of currently and the stealths are just 4cc smaller than the stock crap.
