Dirk,

Correct,
All 327 small journal (2.299 mains) were 2-Bolt Main Caps.

Not sure on the block casting #, but some of the early 327 small journal blocks had a higher Nickel content, making them a bit stronger.

You could tell just by the way the boring bar tool bit sounded when you were boring out a cylinder, to know it was a harder block.

Both Raven Rock & Riverside were 1/4 mile.....Riverside went to 1/8 mile in the 70's. Raven Rock was the home track of Gordon Collect & Rodger Gustin.
