Yet again more W2 360 talk

What is wrong with the heads that needs repairing? Cast iron is extremely difficult to repair as well let alone welding up the head. I am using quench done pistons in mine. Kieth black and icon both have dome pistons for open chamber heads
They are cracked in quite a few spots. Most most is on a bolt down corner but I have talked to a cylinder head shop in Kansas City that says they can repair them. These are also the aforementioned domed pistons I was talking about. TRW 4007042 pistons.
