Does anyone know the exact exhaust port dimension on the Evo 9 head?

I'm getting ready to port my spare manifold with a buddy and I'm trying to find the exact port dimensions that the exhaust manfold should get ported to.

Thanks

the inlet ports to the manifold are match ported to the head for the most part..., you can port the outlet of the manifold a lot where the turbo bolts up
you can clean up the inlet ports a bit, but your not going to want to take much meat off.

pm me your email address and Ill send you a drawing I have of the exhaust port dimensions into the manifold if you want it... you can print it out 1 to 1 and compare to the head

 

Thanks, all i needed to know I will just port a small bit then.
