Towed it home and pulled the head only to find a good head gasket but a hole in the block deck on number 3 between exhaust and intake valve. Looks like it had been repaired some how and it failed. The engines is a fairly fresh rebuild, .40 over with new valves and seats and ran good. Please look at pics and see if this is repairable. Looks like you could tap the hole and plug it but don't know if it would last? comments please.

This is a typical example of where metal stitching would be useful.
it's an indispensable necessity on old engines as yours. Especially Model B engines are more prone to crack. I would recommend removing the valves and cleaning the deck to magnaflux it. Cracks may have traveled to the valve seats.
