A substantial part of my OCD was masked over ten years as it was directionally proportional to repetitious work ethics as a Navy F/14A+ & FA/18 mechanic. I'm trying hard every day to adjust to normality, it's a never ending battle LOL...
I'm a old school nostalgic muscle car guy, this is my third Harley, first one changing cams not a custom to roller lifter..... buuuuut old school solid's oh yeah!

Do not argue with an idiot. He will drag you down to his level and beat you with experience.

There were some early manuals that called for them to be "directional" and the bikes wouldn't have them the proper direction from the factory. HD has since revised that to pretty much what I said above.

Not on a Twin Cam. It only matters if you're reusing them to keep the wear patterns the same. New lifters (excluding woods directionals) can go in either orientation. The lifter bore gets 360 degree oiling to the feed. Even then, it really doesn't make a huge difference.

Your 103 manual is going to say what the correct 88cid manuals say: "To preserve existing wear patterns, orientation of the oil hole (inboard or outboard) should have been noted during disassembly."

Frankly, that's just incorrect. No matter what some Joe-schmoe youtuber says.
