mis-matched cam caps

I have an interesting issue on a head i'm working on for a friend. The head was from an unknown bike so of course I want to check everything. It was in a very dirty state, probably sitting for years collecting grim until he bought. It appears to be a KZ1000 by the caps. We ordered a set of cam bushings (OEM) and I checked the clearance with Plastigage and those were from just under .002 to just under .004 so that is good. I slowly installed the caps while turning the cam and they began to lock. So looking at things it appears cap 2 and 4 are tight towards the front of each cap. I installed 1 and 3 by themselves and the cam turns freely. But when installing 2 and 4 they begin to lock up. So just out of curiosity I turned 2 and 4 around (arrow pointing backwards) and the cams rotate freely. Humm. The intake cam has just the slightest drag in one spot while turning but I can turn both with one finger. As you will notice the intake took a another nudge to rotate on the clip but not always.

So for all you guys that have worked with mis matched caps would you run them with the 2 and 4 turned around. Im pretty sure I would have damage if I were to run them in the correct orientation.

Are you able to bolt the head down (may have a twist that will correct when in place) and see how it is then 

As soon as I get studs but looking at the tight spot which is just above the center line of the two right caps I would think it's not twisted. 

I had to do that with the head I'm running now. Works fine.

Meaning you had to turn the caps around.?
