Ok, well after it set all night, I cannot spin the pushrods like you mention. I noticed that some I could, and some I couldn't. Of the ones on the base of the cam.
The lifters from #1 when I removed them, the plunger was pushed clear up to the snap ring. Plus they were holding the valves slightly open. I'm learing about hydraulic lifters, but I don't think they should be like that should they?
Thanks again for all the comments and info.

Go ahead and order lifters...
I don't know how to read this. Do you feel like I'm wasting money buying lifters, or do you think I messed with it too much and really need lifters? I'm tired of chasing my tail.

You need shorter pushrods on some valves, plain and simple. If you don't have adjustable rockers to compensate for variances valve to valve. There ain't anything wrong with your lifters.
Hopefully you didn't hurt a lifter or cam lobe by running it with not enough lash. They all should be checked. Easiest way is with the intake off. Set em once and forget about them for life of the motor with a hydralic cam with adjustable rockers. You need to take a adjustable pushrod and see what length you need and compare that with the pushrods you're running now. I bet there too long.

Alright, I see what you are saying. If the plunger in the lifter is up at the top pushing on the snap ring, would that still indicate too long of push rod? Thats what is confusing me, I can see if they were way down in the stroke of the plunger. But these are up against the snap ring. I thought that they lifter was supposed to run partially down in the plunger stroke. That way they could compensate for wear. Is this wrong?
I'm sorry I'm being difficult. I've worked on diesels my whole adult life, and they sure a heck don't have hydraulic lifters or carburators.

If the lifter is at the top of the travel against the snap ring the push rod is too short. You have to preload the hydraulic lifters somewhat. Some times the push rods are too long they push the plunger so far down in the bore that they bottom out the plunger then the person adds the 1 to 2 turns of preload and they are holding the valve open. This would be like preloading a solid lifter.

Ok, so if the lifter plunger is against the snap ring, the push rod is tight, and the valve is slightly open, and the lifter is on the base of the cam, what do I look at next?
