NO COMPRESSION WHEN ROCKERS TIGHTENED

Really makes no sense then if everything is right you should be able to torque it and 30 degrees and it should be good.

The long rods go into the exhaust valve rockers, I wonder if I accidentally reversed one, I don't think it would be enough to kill the compression of the whole engine, just seems very strange.

It would only effect the cylinder that it was reversed on. But if the rods were reverse tightening them down to spec would loose compression like your getting.

Push rods are in correct order, the remedy was to let the lifters sit and bleed out with the push rods tightened to 124 inch pounds, once that was done there was compression, apparently if the lifters expand with oil without the push rods they become solid until the oil is out of them where they can move again.

Yes, as close to 30 degrees as I could, they felt pretty tight.

I have never seen a lifter do that on those engines.

Could be because of the anti freeze mixed with the oil, the mixture is harder to bleed out of the lifter than it is for just oil.
You take any of the lifers out and try as hard as you can to push them in and not one of them budges. What gave it away was the fact that whenever I would tighten a rocker the lifter had no give but the valve would move.
