Some very good info has been brought out here so far........thanks.

On the subject of assembly lubes, do you guys have a preference? I have some that are sort of like thick black graphite (almost like grease) in nature and some that are red, more like thick slippery oil. I have used some by the cam makers too, which I use to coat the journals, lobes, and bottom of the lifters. Any preferences there?

When sealant is used on some threads and lube on others (as in doing a cylinder head) does it change the amount of torque you apply to each? I guess what I am asking is, does the sealant change how the bolt reacts to torquing? Hope I am being clear on that one.
