A couple more references on assembly lubes:

https://blog.amsoil.com/what-is-assembly-lube/

"Once you start the engine and oil pressure builds enough to lubricate the engine with oil, the assembly lube’s job is done. It now must make way for the motor oil to protect the engine. If it’s excessively thick, however, it can clog narrow oil passages and prevent good oil flow. The lube needs to dissolve in the oil and leave little-to-no trace of its existence."

The FM/Sealed Power assembly lube works very well, and the properties stay in place for long periods of time:

"The prelubes have special additives which withstand the extreme pressures exerted on cams and lifters. These easy flowing petroleum based lubes function as oil additives, which will not affect oil viscosity. They also hold fast to surfaces on which they are applied and won't run off like engine oil, even after prolonged storage time."

Moly clogs filters & passages. If you need to have a 'visual' image of the 'grease' staying in place, and use moly, just be aware of the procedure of changing oil & filter immediately after initial startup. But just to say, you turn that engine over by hand a number of times before you start it, so that 'visual image' gets wiped away regardless.

As stated in the one comment on Amsoil, the initial protectant needs to get out of the way within a reasonable time to allow the oil to reach the part. If what you use prevents or delays that, it can have negative impact(s).
