We have used a little of everything. From Clevite, Childs&Albert, E.O.S., Isky Rev Lube, Brad Penn, Lubriplate, and I think Micron Moly. Our recent windsor build we used Brad Penn assembly lube for almost everything. I was a little dissapointed since the build went a little slower than planned, I noticed after some time most of the lube ran off of the cam lobes and such.(hyd. roller) There was a thin film left and some dripping left on the bottom side. I think my favorite lube that stays put and won't run is the Isky Rev Lube. Great for cam lobes(especially flat tappets), dist. gears, etc.
FWIW, one night I was watching an episode of How It's Made: Dream Cars, and they featured Koenigsegg. During the engine assembly which is a twin turbo Ford modular based design, I caught a glimpse of the guy using Lucas assembly lube on pretty much everything.
