Any spark plug considerations?

Any particular plug work better with Alky than others? Running just regular AC 42s right now. Are they OK to run w/alky?

I have always had good luck with Autolite 23 or NGK UR5. Every combo is different and if you are running "x" amount of boost and are not having any issues then keep what you have. Just stay away from platinums on our cars....

Yea, I've never run a platnum or NGK on these cars. Was just thinking that some cooler plugs may not like the meth.
