There has been some skepticism on the flows claimed out of 906 our heads. I'm willing to put up some proof. For a qualified big block F.A.S.T. competitor that thinks they could use a better 906 head, here is what I will do, I will supply a pair of heads to test. I will not ship them to you, I will deliver them. Please understand, I am on a limited budget and live in Idaho, traveling to the East coast is probably out of the question.

Put your engine on the track or dyno (engine or chassis), run it and then pull the heads. I will drop our heads on your engine and you can run it again and see what happens. If you don't like the results, we'll box them up and go home.

I don't have any maximum effort heads ready at this time, but the ones I do have are stock gasket port windows and flow, 292 cfm @ .500", 323 cfm @ .600" and 332 cfm @ .700". Whereas a box stock Edelbrock Victor on our bench flows, 277 @ .500", 305 cfm @ .600", 324 cfm @ .700".

Just putting out the offer to see if there is any interest.
