Burning lots of oil, good compression, checked pvc and new valve seals
So the previous oil change was about 4 months ago and i did valve seals and new springs with it i know i installed the seals wrong so this oil change i went ahead and did new ones, since then (about 2 weeks and 800 miles ive burned througha quart of oil, i checked the inside of the intake and it has very little oil residue also pulled the intake and didnt find any oil on top of the valves, i did a compression test and had numbers between 160-175psi any clue here? i wanna say valve guides but i just dont know where to go from here

First question I have is what do the spark plugs look like? This is he first thing you want to check. That might tell you which cylinder is the culprit and also you can normally tell by the oil on the plug if its getting past the guide seal or coming up past the rings. With only a qt per 800 miles, you might not see it with the naked eye. But with a magnifying glass and bright light you can usually see what each plug is seeing.
There are many sources for plug reading but this one is pretty simple.

Did you have any port work done to your heads? If so, was thread sealer used on the rocker bolts?
Sometimes port work exposes the rocker bosses and oil leaks past the rocker bolts on ported heads. Typically see it worst on the intake side
If heads are not ported, disregard.

The plugs are white but about 4-5 of them have oil on the threads, as far as heads go they are stock 706 head with trunnion upgrade and prc .660 valve springs with titanium retainers, I burned 4.5 quarts last oil change without realizing until my oil pressure started bouncing around I added a bunch at the gas station.

+ 1 on the heads if they are ported. Mine are and I have oil on my plugs too. Im going to take the rockers off, clean off bolts, clean holes, and re-apply Teflon paste.
Oil consumption got worse with heads+cam in my car. Its pretty normal for 99-01 ls1s to consume a lot more oil.
