I would say your valve on that side are bad. You should do a valve job on both heads or buy some after market ones. Like AFR's or Trick flow

I've had two cases in life when my vehicles have shot flames.

1st case, 86 2.8 Camaro, 5800rpm no lift shifts, had a little valve float. Guy in Honda asks if I have nitrous. Yeah it was shortly after F&F came out.
2nd case, 94 Z28, bad opti, lots of uncombusted fuel=fireballs.

Um neither sounds like what you have going on. Except the valve part.

Well then it is burning more fuel with the spark rather than burning the unburnt fuel in the exhaust, no biggy, u did good.
