What plugs are best for these heads? Currently running NGK TR6. Just wondering what others are running.

That's what I've been reading. Might give them a shot.

103's here, .032 gap, runs great

I've used both the NGK and Autolite plugs with good results gapped at .032" they are available at the local auto parts stores and inexpensive so i change them often even though i don't drive the car that much. :smile:
