Well I pulled the heads off the motor this morning. Surprisingly the block itself looks to be in really good shape. You can still see the hash marks in the cylinder walls.
The only strange thing I found. One pushrod was kinda ground down on one end. I'm guessing it had the infamous lifter tick that a lot of these engines have. Everything else looked great.
A few cleaned up bolts and pushrods
Then I took the heads, valve covers, and rockers to work and started cleaning on them every chance I got.
Here's one head that I started on
And finished valve covers and rockers. They cleaned up great and all look to be salvageable.
Then I pulled off the valley cover. Yeah there's a lot of sludge in there too. I'll probably strip the block this weekend and take the block to a machine shop to get it hot tanked and checked out.
