Plugs for ally?

[streetknight]

I remember to start gap@ .032" but do I need 43's or 42's? Be running 18 psi to start tuning, but chip is for 22-24 psi and where I will hopefully get to

I've had good luck with NGK UR5's in my GN, Gapped tight .032 & never had an issue with 30#

5's or 6's.. the ac's 43's.. basically any cheap plug one heat range colder than stock. Gap them .030 - .032

Autolite 23R's gapped at .32.

Regular 23's never missed a lick for me in over 10 years and these seem to be a little better.
