I have a buick with a 67 turbo , champ alum heads, 212 roller cam 55 lb injectors precision f/m , smc alky, and I want to know what plugs should I run?

AC Delco R42TS plugs should work fine. I've been running them for years with no problems

Umm.. I am pretty sure the AL. Heads take a different plug. I don't know what it is but I am pretty sure a R42TS will not work.

For the Champion heads I use a Autolite 133 or NGK 4554.

I like the NGK's better

Good Luck
