Valve guide base washer and shims question?

I'm in the middle of redoing my motor. I removed all of the valves so I could clean and repaint the head. I made the mistake of mixing up the valve guide base washer and shims when I took them out. The shims are with the correct base washer but I'm not sure which valve guide they go to now. Kicking myself for not being more careful in marking them when I took them out. I'm at the point now where I have lapped the valves and I'm ready to install the valves and springs in the head. How do I determine which base washer and shim go to each valve? I looked and the manual and didn't really see anything that covered it. Thanks for any help.  IMG_6829.JPG IMG_6830.JPG IMG_6831.JPG

I just measured the pistons and they are at 65mm. Does that mean this motor has been upgraded to the 836cc? Would that explain the shims on the valve springs?

Here are pictures of the piston and the cam. The cam has "Norris cycle R" engraved on it. Not sure what that's all about. I just want to get the valves and springs put back correctly. IMG_6836.JPG IMG_6834.JPG IMG_6833.JPG

Sorry I can't be any assistance to your valve shim question but 65 mm would be and 836. Also Norris was irreparable cam grinding company I believe the our grind is 357 lift 280 duration

They were probably trying to set seat pressures so the valves will not float till much later than stock . Check all the shims , did they use all the same shims for all the valves or does it vary ?

I talked with Ken at cycleX on Friday and he had some insight into the cam. He said it was a Norris cycle cam with an R grind. He had some specs on it also. Valve lift -intake .350. Duration 252 degrees @ .040. Lobe center = 106. Valve is 5 on intake and 6 on exhaust. He said it is a mild performance cam. I haven't worked much with cams and those numbers unfortunately don't mean much to me. I've added the measurements to the picture of the shims. The group on the left are all the same. I believe these all came off of the exhaust side and that is where I have put them back. 
I know #6 came from the second from left in the picture so that is where I put it back. I think #5 was from the first intake on the left but I'm not sure. So really it's #5, 7 and 8 that I'm not sure where they go. Any one have any ideas given the size of those three which would be the likely spot? Thanks for any help. Just want to get the motor back together.  IMG_6829 copy.jpg IMG_6841.jpg
