After checking for leaks it will be installed and driven. I will cut the filter open at 500 miles to see if I destroyed it. It just seems to me that a build using roller cam/valve train and checked for proper clearances doesn't have a need for assembly products just an oil that provides a proper film strength.

Please tell me the mains and rod bearings aren't dry?

Common knowledge: Most engine wear occurs at startup. Why do you think that is?

Chit happens, that engine you just assembled could sit for 6 months, a year, or several years for that matter. One simple step, why not?

Even if it's just engine oil, use something. And if you use something, one step further, why not use engine assembly lube? A product specifically to be used during engine assembly. That's what it's designed for. You spend X for all the parts, all the machine work, assemble it yourself to make SURE nothing is overlooked, so why would you not use assembly lube? Five bucks. It CAN'T be about the money, right?
