It's on a 512 low deck. 10.5 compression pump gas street engine I'd use NGK 6987. If it is a race engine or boosted or something else then you might want to go a step colder or tighten the gap.

NGK makes at least 10 plugs in the 6 heat range that will fit those heads so you have lots of choices. Summit carries most of them but buying from NGK direct is usually cheaper than Summit.
