a guy is tryen to sale me Lt1 heads that he had on motor that he had wet kit nitirous on it #7 cylinder he melted the pistion on it the head above the cylinder had a little melted metal on the head and it put a few pin hole on the do you thank the heads is steal good he said a value job and get the head deck and they will be ok what do you thank would you get them or leave them alone

 

Buy them on the condition they pressure test ok.
Figure pressure test, surface, serti valve job, guides and seals, they'll be like new.

 

Aye, theyll likely be okay, BUT you might want to ask a shop if they will in fact clean up via milling alone, since someone will be pressure checking them anyway. Doesn't sound too bad from your description however

 

How much you paying? You can usually get good heads on Ebay.com for cheap.
