Weird 1991 exhaust valve issue

Hi all, yeah, a strange issue with my 1991 kdx 200 exhaust valve. This is a bike that was a basket case I'm fixing up. I put the KIPS valves in the cylinder (fresh Powerseal job on cylinder, steel exhaust valves, new o-rings in KIPS parts), and they all work great until I put the cover on the front exhaust valve. When I tighten the front cover, the KIPS system binds to the point it won't move. I'm sort of lost here and any help would be appreciated.
Thanks in advance-

Are the bolts too long?

I'll guess you don't have the center valve lined up on the teeth correctly. It has been a long while since I did one, but getting it lined up was a bear for me.

I followed the excellent instructions in the thread linked below for making sure the KIPS valves were installed and timed correctly

I have the same issue, did you figure it out?
