Interesting details have finally surfaced.
I started really looking close at the heads tonight and I've found that some of the valve springs are holding very low seat pressures. Like only 20-30 pounds. So that could definitely be a problem.
So I'm gonna buy some mild performance springs from comp.

I've was running a sealed power cam, lifters and springs. But I want to put my summit cam back in. So upgrading springs would be a good idea anyway. And really these are only 50lbs heavier closed.

It was my screw up. It's really weird cuz I tested all the spring pressures when I put them in 8 months ago. They were new springs and they were holding new pressures.

Well at least you'll know not to make that type of mistake again. Well We've all made dumb mistakes building motors and forgetting a little 25cents bolt/washer or spring that was really needed inside the engine
.Well now it's the old double check trick. It works best when you sleep good and have those bad dreams that you over looked something and do you recheck the next day
