Better core block for sbc 383, 4-bolt flat or 2-bolt roller?

I was planning on building a 383 out of a 1973 4-bolt main block that I picked up in pretty good shape. I went to buy a set of 98 vortec heads, and the guy threw in the block for free, so I said I'd take it! It's a 2-bolt main, but being from 98 it is a roller. He said that he pulled the motor when he heard the bottom end making some noise. I haven't gone thru everything yet, but I did find a nice 1-inch metal shaving in the oil pan to support his claim. I obviously have not had the new 98 block inspected yet, but all things the same, the question is... Which block would you use to build a torquey 383 for the streets? Thanks!
