GMPP Fastburn head blueprints/schmentic
 

Having a custom manifold built for my GM Fastburn heads (part# on heads 0-12367712) , the builder has never built up any thing specifically for the Fastburn heads. He is thousands of miles from me and my heads and wants all kinds of measurements. Called GM and the answer was "we should have them somewhere, but I don't know where".....

So does anyone out there have or know where to get drawings, blueprints, CAD drawings,,,,anything for these heads.

Thanks Dennis
