Using 14mm Plugs (Auto) with Slick Mags?

I’ve seen this question pop up on forums: “Can you use 14mm plugs with Slick Mags?”

The engine I have for my RV-8 is a zero time O-360 (B2B) from Schmidt Aviation in Florida (@ FXE).  It is set up with Slick mags and uses 14mm Auto plugs.

This is just a short post and photo of that about the plugs and Slick combo as opposed to the more common EI with auto plugs.

It was test run at Schmidt has new cylinders, fuel pump, oil pump, and starter.  Everything else is re manufactured at Schmidt.
