Autolight 103's for the street, 3932's for big boost and c-16.

103 are tapered seat, the 3932's are gasketed.

Are you running GN1's or the new GN1R's which use a smaller 12mm thread?

Aren't aluminum heads suppose to use the gasketed plugs? Multiple plug changes with taper seat plugs will gall the head.

I use the autolite 103 "copper core" plugs.

when ordering, you should ask for 97+ buick 3800 plug. The series II plugs are the same (lenght, thread) for the GN1 R (LAC2) aluminum heads.
