The owner gave me the casting number.

They are those.

I called Ford Racing they said they have not been given flow specs on them, but an unbiased outside source said that they will flow arround 250 at .6 and 190-200 with potential of 315-320/230-240.

Ill have to scrounge arround for a complete flow sheet. I wont be running them at .6.

So since they are 10 degree heads, what manifolds are available for that? The instructions pages that are on that link above says they allow fitment of currently available intakes. http://www.fordracingparts.com/downl...-6049-N351.pdf

Im a little lost here. How can it be a 10 deg head but use a regular 23* or whatever it is intake?

u r correct they do have potential to flow alot of air. they are used in ALOT of roundy roundy stuff. the ford Z head is actually an aluminum kind of "updated" version, same basic offsets and such

Nevermind, I changed my mind about it. Different plans. Thanks for the help.
