What plugs are good for steel Dart Platinum heads?

Spark Plugs

Kev, I use AR12 or AR13 Autolite , depending on the heat range you need. They have the tapered seats not the flat gaskets.

We used AR 133 or 134 plugs...That is a NGK 5673-8 plug...If we were still running Dart Iron heads I would have switched to the NGK's...We run NGK stuff in our aluminum engine now...
