 None of you iron headed FE guys caught the spark plug thing at the end ???  FE guys from the other sites have been asking questions.

I'm over here, too.

I have a follow up questions on it:

What is the new angle that you used and will it clear the tall ex port?

The part extending, into the chamber, that's a adapter, with a 14mmx1" SP in it?

Can you give us the approximate HP increase, using it?

 No angle change just more projection. Yes an adapter. On the 289 it was close to 10 hp on the top end.

You mentioned that there was some issue in manufacturing it or the fit? Can you tell us about that?

Could you use brass to fill it in, even more and blend into the seat, making it permanent?

  No, the way I used the early versions I had too make them essentially be part of the spark plug to be within the rules.  To manufacture them I want them to be a part of the head.  But also be be quickly removable is so desired.  Like I was saying in the video I did a redesign of the part that would be the way I would have preferred to use them during the Challenge but was not able to.
