Update: When I changed the oil last night, I decided to pull the oil pan to check the oil pump and bearings. The 2 rod bearing caps I pulled off basically looked like new as you can see. I couldn't find my Plastigage to check the clearances but I'm sure it's fine.
However, I did find that the oil pump's pressure relief valve piston had a slight rough lip on it that prevented it from sliding freely and possibly seating completely. A few minutes with a file and 400 grit sandpaper fixed that.
I also changed the oil pump pickup tube gasket while I was in there for piece of mind since it was so cheap and easy.
The results? At the same oil temp (185 degrees) oil pressure at idle is now slightly up to around 15 from 13-14, at 2K RPM it is slightly up to around 53 from 48, and at 3K RPM it is up significantly to around 78 from 70 max. Pressure still maxes out at around 80-85 at full throttle. Now it basically holds steady at around 80 from 3K RPM up with a slight drop as VTEC kicks in.
Same oil that I have been using (Pennzoil Ultra Platinum 5W30), only difference is this time I used a K&N Performance Gold filter instead of my usual Wix since the parts store was out of Wix, but that seems like way too big of a difference to be caused by a different brand of oil filter alone.
As good as the bearings looked I'm not worried about this anymore. Thank you very much to everyone who responded, your input is very much appreciated!
