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.
good point.

I GUESS WHAT IM ASKING IS COULD I HAVE BEEN OF A TOOTH OR SO OFF WHEN I PUT THE DIST.BACK IN AFTER I LOCKED IT OUT?I PUT IT BACK WHERE IT WAS OR I THOUGHT I DID.I WOULD LIKE TO TAKE IT OUT AND REINSTALL IT.TO DO SO WOULD I GET NUMBER 1 TO TDC(0) AND THE MOVE THE BALANCER TO 34* THEN DROP THE DIST BACK IN MAKING SURE THE ROTOR IS POINTING TO THE NUMBER ONE PISTON.
he says here that it has a little miss @ 34*....just saying

The point being, a miss due to a broken piece of the valve train is typically going to be RPM dependent, and won't change with ignition timing.

without looking at the car, you, are myself are just giving best guess.

the video of it running you ask for would help.

I'm thinking a crank trigger would solve the problem ,but that is me.JMO

I agree on the video.. Without a video, his best thing to do is just start R&R'ing parts until he finds the faulty one.
