olds head interchange

Does anyone know where I can find interchange information for a 57 OLDS 371
I'm specifically trying to find out if the rockers shaft brackets from a 51 OLDS 303 head are the same as the 57 371 or if any other year will work.

No, they're not. '52-'58 rocker parts should interchange, as far as stands and arms go, although the '57 shafts are slightly longer, and the end stands are different.
