If the springs wind up being correct, then as said before, you're gonna have to either take it somewhere to be checked, or start swapping out parts one at a time until you find the culprit.

You could have a spring broken. Mine did what you say yours is doing and it had less than 30 passes on some Manley springs I pulled the stud girdle and found one spring had the inner spring broken. Impossible to see without really looking. Just a thought.

If it's broke you will see it when the girdle is off. I was looking for electrical problems too when mine did it.I found a small chunk of metal laying in the head, that's when I took the girdle off and looked at the springs. Mine would do fine free reving and in the burnout box but would start cut out about 6500 rpm going down the track.

Guys, lets get back to the symptoms.
He said at 34 degrees, there was no issue. At 36 degrees, a miss occurs.
A broken spring, pushrod, rocker isn't going to cause a miss with a change of 2 degrees of timing. A broken part will cause an issue at all times, no matter the timing change.
