. . . It seemed like when I would get 2 or 3 (of the 4 shims, each side), right, then there would be at least 1 wrong, so I would switch that one wrong shim, and they measure again, and they they would all be wrong. . .
I don't want to second guess what you are doing, but is it possible that not all of the cam saddles are torqued down properly?
Anyway. . .least it is moving along.

THe intake side was giving me BIGGGG trouble and was frustrating me, so I moved to the exhaust. In the middle of the exhaust side, I realized the the proper torque setting are mandatory. OOPS. So doing the exhaust side, I made sure they were always torqued properly (9 ft. lbs). I since have not gone back to the intake, so maybe that was my problem?! I sure hope so. I am going to check it out tomorrmow
As for the post before- you are right, I believe I will have to go up a size or two on the mains. Right now, I have a 11.5 (don't know what that # means exactly), and then I also have a size up which is a 11.8. The 11.5's are in the carbs now.

Well, at least I found out what sizes I need for the intake.

Dude, take a micrometer and your shims with you to some off-the-wall repair shop. Sometimes dealers are ok with this too.
Trade what you have for what you need. Tell them anything . . . I know . . . Tell 'em it's a school project you're doing for your Dad for a Father's day present.

Anyways, would re-grinding the tip of the valve, oh say, 8 thousands (or whatever the gap calls for) be a bad idea? If I grind the tip of the valve, it will lower the bucket, and be the right height. I don't see how this could be bad?

When a valve seat has worn to the point that there's not a small enough shim available to place in there and get a decent measurement, then that's the time it would be necessary to grind the tip of the valve.
