while you are doing that i would at least take 1 intake spring off and look real good at the locks, retainer, valve stem and spring

^^ Agreed!! ^^
That is the best advise so far and that is an easy thing for you to do now that it is off the dyno. Take (at least) an intake and exhaust spring off and apart, when you pull the rockers off, look at the valve tip pattern. Assuming there was enough run time, personally I've never seen a happy valve train that had the "star" pattern on the valve tips, and/or galled locks / retainers / spring tails.
I found Dynoing engines for the general public is many times torture regarding mis-matched combinations that need to be sorted, so I've seen a lot that need help. Not saying this is the case here, but the way that noses over, I would not be surprised if you found an issue.
If you go back to the dyno, always mount a timing light so you can monitor what's going on during the pull... it is a quick way to rule out an ignition trigger issue.
