So after doing a ton of reading today, I think I realized that I may have two PCV valves.
The previous owner put in a new "PCV valve" up top at the intake manifold, and I've been reading that normally this is just a black elbow that is a straight flow 90" piece and that the "actual" PCV valve is at the chamber box underneath the intake manifold.
I noticed his PCV valve replacement for the top one was a typical aftermarket replacement, and that the one at the chamber box appears to be original. I plan on ordering a genuine Honda one for the chamber box and fabbing up my own "straight flow" piece up top. Until then, does having two PCV valves (and one possible bad one) seem like a reason my idle will occasionally dip?
