Spark plug question?

I was running e3 spark plugs on my 350 gas engine, and realized I was flooding the cylinders after a few races, I made some corrections and decided to lean out the motor a little bit, via smaller jets and power valve. The spark plugs were saturated, and decided to run ac delco for the moment. Would anyone suggest going back to the e3s or just run something different? Any suggestions would be helpful.

I run cheap ass Autolights in my methanol motors. Change them mid season and go.

E3's are nothing but the latest spark plug scam among many in the last 60 years... I don't know anyone running a race motor using them. My engine machinist just laughs when anyone mentions them... But it's your $$$.

Autolite racing plugs have never let me down

Using the same autolites for over 9 years. Just bead blast regap and move on.

I know a certain engine builder who is sponsored by E3. Little secret....Runs NGK or Autolites in his race motors. Shhhhh!
