Need Racing Spark Plug Info

[gnxtc2]

Nick, I called autolite and the tech said that the AR 3934 and AR 3935 are gasket seat plugs and that the gn1 heads take a tapered seat plug.

Is this information correct?

I would rather have a washer type plug on an aluminum head. After many plug changes, the tapered seat could get galled up.

I run NGK R5671A-10 which is the equalivant to the Autolite AR3932
