Default Need some help with exhaust manifold numbers please.

I was cleaning out the garage and sorting out my corvette stuff and ran across 2 exhaust manifolds. I was wondering if anyone could help me with the numbers to tell me what they came off of?
The first one is
393 2461 and has RH 20 on it Believed to 72 200 horsepower.

The second has
338 711 RH 4
could be as late as 81, but not sure

Any help would be greatly appreciated!
