After getting the intake manifold off I found a nice size hole in the block right next to the oil trap box with a rod sticking out. Lol Surprise!

Crusher. If it were turbo, I'd save it with an engine swap.

This video explains how my car was maintained prior to a #4 cylinder exhaust valve burning. To my knowledge the engine has never been opened. Has good compression (except #4), and still has the original cam seals.
