You want to go with the non projected type plugs like BR6ES, BR7ES, BR8ES.

BR6ES = Stock to 20psi
BR7ES = 20psi to 35psi
BR8ES = 35+psi

Non projected plugs help fight against spark blow out in high boost applications.

Higher boost, if you experience misses during a pulls, gradually reduce gap starting from 0.26 to 0.18.
