ProComp/Speedmaster aluminum heads

Still on the fence,I need them like a hole in the head but at that price its too easy to come up with reasons to buy a set. If I did I would probably buy the non cnc and get Yr involved and see what we could get out of them,I don't mind aluminum shavings nearly as much.
Having yellow rose CNC Port them is a viable option because he is a bot. He's not human..
