Bored

The cylinder bores are 4.030, so they've been bored to .030 over already.

Given the small amount of scoring in cylinder No. 5, this block will have to be bored to .060 over to get it ready to rebuild.

It's what was expected and a scenario that is better than what could have been given that this engine was sitting for decades.

It's difficult to tell if the block was indeed decked at some point too, or if this counter-exchange block simply came unstamped because the stamp pad is blank. One would assume that this is something that the machine shop will have to determine by measuring.

There is so much to learn.

A visit to the machinist will determine if the rotating assembly needs to be removed before dropping it off or if they will want it together to do measurements.

For now, the heads are off of the block. They will be taken to a local shop for work. We'll pick the owner's brain for the next move.

They are filthy and look like this engine was running richer than Oprah, but they should be fine.
