Hi - My 1978 raw water cooled Atomic 4 has spent most of it's life in the salt. It now has a cracked head. Starts easily, runs rough. New coil, waterpumps, some other bits. I am curious how easy it is to determine if it is a good rebuild candidate. I have heard stories of ppl rebuilding them only to be destroyed shortly after by corrosion. compression ranged 95/105/108/113. Is there a way to inspect the guts/waterpassages without removing the block?
