Porting 596 Heads

DISASTER!

Started on the second Head and within the first two hours I’ve broken through into waster. This head has a few noticeable casting flaws and as you guys can see in the picture there was a bad one right behind the valve guide. It was noticeable quite a bit higher up and I chased it down. Very porous and ground out very easily.

Anyway, I’d there anyway of saving this head?

Would liquid metal work or could it weld up as it’s such an accessible area?
