Hi Daniel
I'm running the original pre-production Pierce head. It uses standard plugs.
They went to the smaller plug when they started production thinking they
needed the extra material around the plug. I'm running 12:1 on pump gas and
it goes like stink. Specs on the car can be seen at http://www.ado13.com I
don't have any of the tech info on the head but it does exist.
