Oil consumption!?

Oil consumption!?
Hey guys,
I have an 05 Dyna with a recently rebuilt top end and cams. Previous owner stepped it up to a 95 kit with cams, no current info on cam type also has SE heads.
Ive had the bike for 1.5 seasons. Found oil consumption to be high 1qt every 400-500 miles. Rear plug is black and sooty while front is greyish. Did a compression test dry @175 front and rear. Wet at 180 front and rear.
Sounds like valve seals to me but any other insight would be appreciated as to why I am consuming so much!
Thanks

The 05 Dynas were included in a service bulletin just after they came out. The engine factory put the wrong valve guide seals in the top end. The heads have to come off for the repair, the rear cylinder sounds a valve guide seal problem, get both heads done at the same time just in case the front goes out in a few months.

So I pulled the heads and I’m replacing the valve seals, the exhaust valve on the rear cylinder was packed with carbon.
But it I also found that the front and rear cylinders had different seals. See my picture below. The black seals were in the front cylinder and the other were in the rear which is where the sooty plug was. ALSO, the heads are stamped 04 but my bike is an 05 is this an issue!!? They are screaming eagle heads.
Also any seal recommendations?

175 dry vs. 180 wet tells us you're doing ok. Rings and/or valves won't likely change your oil consumption very much.
Have you considered it's the oil, and not your engine that's the problem?
Maybe try a different oil? Maybe a heavy-duty engine oil?
Something like Delo or Rotella?

James Gasket Viton seals
I have had good luck with https://www.ebay.com/str/bigbikegaskets and their oil seals (they will sell the vale seals separately, just message them)
