I'd go for it. Remember, a little iron makes a LOT of rust. These engines usually rot out from the inside where coolant washes away the corrosion deposits. A good check for remaining sound metal is when you remove the studs - check the remaining wall thickness. 3/16" or more is OK, less is shaky. Converting to glycol cooling (heat exchanger) will prevent further internal corrosion. Stopping leaks will prevent the external corrosion. One known source of external leaks is that cover plate behind the alternator - change that from bolts to studs & nuts (Moyer has a kit to do this). When I changed to glycol cooling, I also had to upgrade to the ball bearing water pump to keep the glycol in the engine. A raw water leak is no big deal - just goes into the bilge. When you leak glycol, it's like losing blood - you've only got so much!
Oh yeah - buy the Moyer Maintenance & Overhaul Manual.
