...and low oil pressure and very poor top end oil flow...
Maybe we're trying too hard at avoiding giving out bad news, hoping he'll realize it himself first
Yes, it's time to take it all apart and rebuild it. A heavier weight oil will just be a band-aid while he's figuring out how to accomplish an engine rebuild.

Im convinced I need to pull the valve covers off and make sure I tightened everything down properly and have everything put in there correctly. I will update everyone on my finding later tonight. thanks for the help guys.
Switching from 20w50 to straight 30 made my oil pressure worse actually. This is crazy, and now another lifter is ticking.

To be expected, as SAE 30 is lower viscosity than 50. You could add a thickener such as STP but go easy on cold starts as thick oil doesn't circulate as well when cold.
Noisy lifters are mainly just irritating noise, but if you hear deeper, heavier knocking better park it before a rod makes a window in the block.
Oil to the rockers is metered by the cam bearings so I don't think you'd gain much with another restriction, plus you could starve the rockers. How much oil is reaching the top end now? Run it with the covers off and see if it's flooded with oil or not. You should have some oil dripping off every rocker arm.
390's send oil from the pump to the cam bearings first before the mains and rods so if your cam bearings are worn, pressure will be lost before getting tot he rockers or mains or rods. You're only a month, six weeks from your March overhaul date so just keep driving easy and it should last. Enjoy the ticking!

I agree. You would have to put in small restrictors to build up the oil pressure, if it's even possible. At that point you would starve the rockers. There aren't really any band aids for a worn lifter/cam lobe and low oil pressure. Main reason for the low pressure is more than likely worn main, rod and/or cam bearings. If thicker oil doesn't help, it's repair time. Maybe borrow or rent another car if you have to wait until March.

I hope the rebuild went alright. On my oil gauge the 20w-50 and 30wt performed very similar results. I don't think VR1 has enough of the good stuff to properly protect, but it is a last result option in my opinion. Not suggesting it because you said you are/were using it. Sounds like you were going through a similar situation as I was, but that little midget with a tiny hammer was constant and did more damage although my engine would give you an oil bath. I know FE rebuilds are expensive and again, I hope it went well for you.
