A quick ball hone with some PB Buster. A bath in water with DAWN dish soap. Blow out all passages and heat the block up with a torch and let it air dry.
I'd maybe have them square deck the block true. Factory spec's were a bit lax.
Just clean the BOOGERS out of the ports of the head.
I'm grabbing all of it Saturday. And after 20 years of NOT having a project car for myself and always doing others. I'm gonna have to buy an engine stand lol. The rest I'm covered.
