Yikes, block with cracked cylinders. I have two 392 IH Palmer marinized engines in my boat. I have rod nuts, not bolts in the rods. One thing I have heard is you can deck the block to improve the quench and raise compression that way without it pinging.
Good on you for keeping the 392! Hope to see it running again

Sweet IH👍
Looks like it lost some oil psi to me
