Looks like I goofed. After stripping the threads on one of the top flywheel housing bolt holes in the block I proceeded to drill and tap for a helicoil. I was careful to try and stop the drill from going much deeper than the existing hole for fear of hitting the water jacket. But now after putting 100 miles on the rebuild I noticed some coolant weeping from behind the flywheel bolt. Guess I will try some thread sealant on the bolt threads since its clear the bolt hole is now part of my water jacket... Bummer.
