Spark Plugs

[3nracing97]

What is the best spark plug to use on Brodix Heads on gas? I switched over to gas this year and I'm running NGK R5671A-9 5238 right now. Would really like to run an iridium or double platinum type plug but can't find one to fit.

I wrote down the wrong plug number, I'm running NGK 4554.
