beautiful! a work of art. I can only imagine how many hours it must take to machine one. and i bet you are very happy they are aluminum and not stainless steel (it takes so much more time to machine and is hard on tools)  truely a beautiful head. |

Both valve guides are clearly canted in my eyes = superior flow at higher lift. |

I spotted a big problem! Better remove those heads and sell them to me Mexx, they do not fit your car at all.  I also noticed the additional inlet in the intake channels. For injectors, fuel or nos? Perhaps both? Again thank you for sharing. Let us discuss my specs and the price so that you can bring my pair to SCC this August -BB- |

intake & exhaust are canted
Cool, the exhaust is obvious, but the intake angle is very subtle, likely only a degree or so. What were the flow numbers? 369cfm 25" at what lift? |
