thx. I have been reading up on the Nickel MIG products for cast iron (hot method). Using a BBQ grill (which goes up to 500 deg). Also there is a cold method of MIG too. I have a neighbor who is a TIG expert, I will hit him up for his opinion (don't want to give him more work!
). I think I have another non-smog manifold that is cracked similarly to practice on.
