Why are you starting with a 2 bolt main block, 302 came with 4 bolt? The original blocks where 618 castings in '69. I'm not questioning your build, just pointing out different items, but in 1966 maybe they used 2 bolt blocks.
Also, if you are using an older block be sure to test the walls for pin holes. I personally got burned by the pin holes twice.
