If you build a 377 those heads will need steam holes,might have the machine shop drill them now. BTW I think your 350 block is salvageable. Which saves you lots of money,no bore,no new pistons,no bearing spacers. My .02
Machine shop quoted $350 to do the heads for me. That includes some welding for a deep score in the one head, checked, tested, cleaned and milled as necessary. He does not recommend attempting to repair that block however.
