Everything that's been suggested suggested was speculation because we didn't have all the facts.

It's not as if you always get the right components in the box when you order something. There's a reason why you check for coil bind when you put an engine together, particularly with mix-matched components. You do do that, don't you? You degree a cam and you don't have as many components from different manufacturers in the mix as what he has with those springs.

It was just a suggestion, I wouldn't have my feelings hurt if he didn't check, and I don't understand why in the world this should be an issue? Particularly since it can be checked more easily than anything else and we're all trying to help someone, right? Unless you think there's something personal in pointing out that it should be done. It's not like we're in competition, or is it?

"Valves were adjusted by tightening the poly lock until the pushrod just stopped spinning by hand then almost a 1/2 turn, lock down the hex nut and then tighten the poly lock."

You need to tighten BOTH at the same time.....trust me it's way better that way. You may have inadvertantly overtightened it. After I get done, I always check the lash on every one once more just to be sure.

If you dont know the history behind te stock rocker arms, I would suspect that the rocker arm(s) may have been at one time overheated due to oil starvation at the ball surface.This may have caused the rocker to get "heat treated" resulting in a loss in ductility/strength. I saw this once on a funny car rocker arm from excessive grinding.

If there was contact with the valve to piston or spring collaspse, I would think the push rod (assuming the weaker component) should have bent, right? Of course, I'm not ruling out other theories, just my few cents worth.
