P90 Head and porting


I am about to dig into my P90 head that I just got. I dissembled the whole thing and was about to home port it. Would anyone be willing to give advice and provide pictures of their already ported head?

I have been researching this topic a lot recently and am trying to figure out the best attack plan for porting. More specifically the valve guides on the exhaust side. Has anyone removed a lot of the material as in the attached photo?head porting.jpg

Im not looking to trade secrets, just where to focus my attention and some photos to reference off of.

Head is going on L28et , holset HY35, MS2 V3, all supporting mods.

Thanks all,
