You already know its a 250 I6. That's really all you need to know other than integrated or bolt on intake manifold. If you don't like the integrated manifolds buy a different cylinder head.

Tell the teenage parts goons it's a 1976 Chevy Nova with a 250 I6... or 1970 or 1971 or 1972 ... Chevy Nova, or Malibu, or Chevelle or C10 pickup. They all came with the 250 I6. If you want higher compression pistons and other performance upgrades it really really really doesn't matter what the block and tins originally came from.
It's your 250 now and you're building it for your truck.
If the machine shop guys hafta know what it came out of before they can bore it out or align bore the main caps or .... then you need to find a different machine shop.
