Basically he had it, sold it to a guy, guy's kid noticed GM bean counters skimped on head bolts allowing the head gaskets to fail, and gelled it up, possibly ruining the IP.
valve covers and intake are off, and that is where he quit, because he is under the impression that the pan needs dropped to pull the oil pump driveshaft to pull the vac pump to pull the intake to pull the heads. I dont know for sure, I wouldnt think that GM would screw up that badly, but who knows.
I'll try to get some pics.
I guess by being an 82 it should have the DX block with the roller cam, so its much better than having a 78-80.
Gelled the engine oil or the fuel up? If the oil is gelled up how long did it sit? Rust is a concern ruining lifters and push rods etc. Gelled oil means bearings are done.
ARP head studs and a working IP set to factory timing will get some life out of the engine with a water separator fuel filter add on. Word is any dirt or water will muck up IP timing bad enough to hurt the engine at it's extreme 22:1 compression.
