Thanks for all the replys. Just quick question before i plan on running it this weekend if weather lets me. When it boggs and i kill it and check plugs , what will i be looking for to pinpoint plug issues? Excessive fuel on plug? thanks in advance

Wet sooted plugs, clean them with a green scratchy pad soaked in good carb cleaning solvent, rinse in clean, reinstall.

Start it up, make sure it is at temp, then hammer down to test acceleration.

If all is good, plan on sending those injectors in very soon.
