Can I use wheel bearing grease on my roller tip rockers and the face of my lifters where they bump the cam? I guess what I'm really saying is will this grease dissolve in the oil and fall to the oil pan on startup. This is a freshly rebuilt engine.

Engine assembly lube is quite cheap, and dissolves when it is supposed to. Using grease will negate the cooling properties of the engine oil on any parts you put it on, and probably plug up some oil return holes. I wouldn't do it.

Yes you can use grease; just make sure it's NON-FIBER, and preferably not moly. White lithium is good, or like Mobil 1, or "blue grease".

However if this is a flat tappet cam, I'd STRONGLY recommend that you use the cam mfr's assembly lube. With as much trouble as people are having with those due to the modern formulations of motor oil, you don't need to add an excuse for whoever not to honor a warranty.

Get a bottle/can of "EOS" Engine Oil Supplement from your local GM dealer.
Coat all the moving metal to metal contact parts like rockers and cam lobes and lifters. It has special anti scuff/anti wear additives. just right for initial run in. Dump the rest of the bottle in the oil.

I think it was sofakingdom who mentioned this before;

moly grease is like little ball bearings, provides a good strong lubricatant. so with two hard surfaces rubbing against each other, this is good - bolt threads/tapped holes, flat tappet cam/lifters

other grease like the ones he mentioned, or Lubriplate 105 I think, are good for hard-soft surfaces, like a crankshaft->bearing surface.

I guess the moly lube is hard, and will embed into the bearing surfaces

Cam-lifters lube (flat tappet) is so scary crucial that I make damn sure to do it by the book. I use the lube that is supplied with the cam, or buy some seperately. (side note, lunati and crane both supplied a black moly paste similar to ARP's thread lube. Comp supplied a red goop that was similar to clevite 77's "bearing guard". hmm, wonder if it was moly based lube or not?)
rockers-valves and whatnot don't take the beating that the cam does, I think I used cam lube at first, then got lazy the 2nd/3rd time and just doused it with engine oil.
