392 head casting number suffix

Post by the-max » Tue Apr 10, 2007 9:17 pm

I have a 392 hemi. he casting numbers for the heads are 1731528-1 and 1731528-2. What does the -1 and -2 mean ? I thought they were side to side interchangable, but maybe I'm wrong and -1 and -2 means left and right. If it's not that, then what ?
