My heads have new ductile iron seats and guides that Bryce installed, I have no complaints at all with the quality and materials in my set of Airwolf heads.

Bryce may (someone should ask him and confirm) rather than speculate. I believe he told me he gets the raw castings and machines seats, guides and then does the CNC work stateside.

I totally RESPECT Jeff, but you might want to confirm whether (or not) his comments were with regard to the STANDARD ProComp SBM heads or the Airwolfs let's at least deal in confirmed information, not here say, fair enough?

I get enough speculation and people going off 1/2 cocked at work, don't you?
