I agree with this statement totally. It is better to start with a 2 bolt block (I have built 14 of these, long ago) and use splayed main caps so the tension/pull is in a different plane than the 4 bolts pulling on the main web only. I have used the Milodon caps and had the block main saddles checked and the machinist I used to use would get everything so close that I would have the block align honed to take out the .0015" that he would get it close to. He was such a great machinist and I was sad when he retired.

Anyway, there are lots of 2 bolt 010 blocks and if it came from a truck with the "camper special" or tow package, it was supposed to be guaranteed a 4 bolt.
