So all of that unburned gas diluted the engine oil which means a lot could evaporate via engine heat. All of that raw fuel into cylinder six would compromise the seal that the oil rings could give you and further accelerate blow by. You might want to check the no. 6 plug as it may be wet, oil soaked or fouled so replace it to not have trouble later. Hopefully no other damage occurred and maybe check pcv for excess blow by as well.
Lastly no offense but high performance engines should by checked often such as every other fill up to keep oil level as close to full as possible which will add tens of thousands of miles to your engine life.
Good luck on your findings.
