New 83 gs850g

I just realized, before I installed the spark plugs yesterday I used some anti seize on them. A crayon stick kind of putty stuff (not sure if it's all the same). Maybe it's insulating the plug or fouling two of them?

Not that it would probably produce those symptoms, but isn't a carb sync needed after a fresh valve adjustment?

Yes. Synch the carbs and see where things go. If the cylinders were all firing before the valve adjustment, and now they aren't, then you know where to start. If synch'ing doesn't help much (make sure to note the initial readings before making changes), then you probably should go back in and recheck your clearances, maybe you misread a measurement. If you haven't already, you might also want to check compression and see where it stands.

You shouldn't need a fuel filter with an oem style petcock, it has a filter screen built into the post. The fuel system isn't designed to operate with an additional filter, so pitching it was a good call.

Ill try to locate a carb sync tool. Compression before adjustment was between 112 and 117psi on all cylinders, ill check again after church today.
