Interesting project! Great to see you thinking it out and getting advice from the "experts". Interesting thread.
Regarding ditching the reverse flow system, the '59 block is a reverse flow block. '60 block is not reverse flow and the water passages are not the same, most notably in the deck. The '60 block water passages cause more cooling water to flow to the back of the engine and up into the heads. The '59 block distributes water evenly into the block from front to back. That makes the water passages different in the deck. I think the '59 block could be converted by plugging up water passages in the deck and making some passages smaller. You should be well aware of what you're doing and know how it is different than the conventional flow blocks.
I considered converting my '60 block to reverse flow but decided against it after learning about the differences.
