If the ignition is ok, and it turns out that the valves are alright the other thought i had was i moved the gas tank to the bed of the truck and the old hardline was pretty nasty i ran rubber line all the way forward temporarily, maybe it is not flowing enough at 2k and that is causing the backfires through the carb? I dunno I am just trying to figure out everything i need to double check before i start it up again
If the mechanical advance springs are (God forbid) stock, or still aftermarket ones, 10 degrees initial is not going to be anywhere near enough timing.

If you don't have a dial back timing light, make a timing tape and use a timing light to see what the timing is at 2000 rpm. If it's not high enough, give it some more timing. I'd use at least 36 degrees w/the engine running at 2000 rpm.

Once the cam is broken in, set up the advance curve.
