The flywheel puller did it. With much smaller bolts, I was fairly gentle on the puller torque, so I gave the 1lb hammer some fairly brisk whacks before it came.
Now that I think about it, a couple other things made me scratch my head though:
I found no other way to clear the oilpump gear on the cam other than knocking out the tappet guide on #1 intake (with the lifter still in it), #1 exhaust of course I was able negotiate because the bearing was then out. This worked fine [despite my hesitance to put steel to steel (didn't have a brass punch long enough, so grabbed a real soft bolt) to steel and whack it with a steel hammer and hope things move before marring or breaking], but don't recall seeing this noted anywhere, nor does it seem to make sense that it would be assembled in this way, but maybe?
Also [I think I was asking about this before, but don't recall the answers]: if I have the block boiled out, do I need to worry about damaging the cam bearings or tappet guides? It seems they should be fine, but sure hate mess up such things when they're good yet.
Finally, I assume the diametral tolerances for the mains are around .003", but I've never noticed a spefic tolerance published. Anybody know? They probably can run pretty loose, but with it tore down this far, it makes sense to me to replace them anyway.
