Engine building questions?????

If you are not installing and firing it right away, I would leave the intake and rockershafts off. WD40 is fine for cylinders..So is ATF and/or engine oil. The cam lube needs to be on the cam. If you leave it and it's a liquid based product, it will all run off in a day or two. So I would leave it off, when the engine will be fired quickly, finish the lube deal, stick the intake on, and fire it. Also, Castrol does not have the zink anymore. If the gold seal on it say "economy/emmissions" on it som,ewhere (I forget the API rating right now) then it's useless for old cams. You can also add a bottle of Comp's cam break in additive to any oil and it will help. I run fleet grade deisel oil. Car Quest 15-40 plus a bottle of the additive to break in cams. Then just the fleet oil. Rotella is the same idea.
