Pull that new push tube and inspect it closely. A ball and socket shouldn't be binding in one spot. Maybe it's been dropped and has a small flat spot or burr on the end. Even if it was slightly bent it should spin without binding unless it's running into something (like a guide plate) along it's length.

After hitting a point where it would not turn over by hand, I took the advice that maybe a valve is bent. I removed the head for a visual. I looks ok, but i will take it to a machine shop in the morning to have #5 looked at. The engine turns over easily now and does not hit a "wall".

Keep Turning it Over with the Head OFF and check the TDC and see if all 4 pistons hit the same height at TDC
Normaly when the Piston Smacks the Valve it wont bend the Valve as they are Parallel to one another and only damage is the Push Tube
ANything is Possible though
Did you even clean the sealing surface of the Block to Heads??? Maybe just the PIC??
Those Valve Look REALLY REALLY Clean on the One Cylinder is that the Piston that had the Bent Push Rod????

That cylinder that is clean is the #5 and is the one that bent the push rod. The block was prep'd clean and level with a carbide blade borrowed from that machine shop that did the surface on the other head. I read to take a hammer and tap the valves to check for binding. I'll try that after dinner.

I noticed when I was installing pushrods, that the lifters bleed off very slowly so you need to tighten the rocker carrier slowly and don't use any power tool for this. Your's would be the definition of bent BTW. I'm still in denial stage, so haven't dug any deeper into my similar valve train dilemma.

Chet, you still down? I know the feeling. Mine runs better since I've turned off the EGR but it still has the miss. It sometimes is almost nonexistent to very noticeably there. I've almost decided to bite the bullet and take it to the dealer........ not ! I'll find it when i get good and pissed off or it blows up and then rebuild it to Mutants of a Monster specs

100% agree.... anything on engine use hand tools....helps prevent stripping of nuts and bolts or breakage. Think of the spark or glow plugs, you would never use power on those to either start threading or torque down, right?
I am anxious to see what is binding on your engine, everything in pic looks alright, but can only see so much.
