Friday night Doug and I dove in down and dirty. We dropped the steering drag link and removed the oil pan. We used a cheap kiddie pool for a catch basin, and proceded to do some serious desludging. We scraped and wiped all the crud from the pushrod gallery, then put the solvent right to it. We pulled the heads, but left the lifters in place as we didn't want crud washing down on the cam. Our goal at this time is to leave the block in place, but that is subject to change as measurements and inspections continue.
We also removed the Fan and the water pump. Pulled the starter, and the fuel pump as well. We know that aspiration and ventilation in this engine was a problem. But we believe that the engine mechanicals are strong, after all we did have it running and she gave us a pretty decent set of compression readings. We are not really going for the "engine overhaul" at this time. We are just disassembling and cleaning. We havent found any reasons yet for major parts replacement or machine shop work. A top end gasket and seal set was only $50 and on the shelf at NAPA
The starter, water pump, fuel pump, heads, and oil pn all came back to Bellingham with me for a good cleaning and a paint job. We do plan on a valve inspection soon. After a good soaking in a lye bath. It might be wishful thinking but the plan now is to hand lap the valves and replace the seals. This engine does not have replaceable valve guides. We might have to get the valve stems knurled, but won't know until we get the valves out.

Sludge is coming off in layers. When we removed the cooling water drain plugs from the block nothing came out. We blew compressed air back up in the holes and it wasn't pretty. Doug didn't think it tasted very good either. We used a lot of brake cleaner solvent spray cans and the kiddie pool is ugly!
I saturated everything with WD-40 and will let that soak for a while. The cylinders looked pretty good at the first glance. The piston crowns appear in good shape. Doug got one of the hydraulic lifters apart and it too looks to be re-usable. We have a tremendous amout of tedious cleaning to do, as our mission is to reuse everything we can and keep the cost down. 
Nice Jugs huh
