How much would this cost? PM if you don't want to post. These would be 220 as cast heads, only want the exhaust and intake ports worked. No milling, and no chamber work unless you see it's needed. (I do not want to raise the current CR, a little drop would be ok if needed).

Porting is not a uniform thing. Everyone who does it, does it differently. Same concept yes, but alot of people have different views on alot of things regarding to porting. If you owned a shop and people called you asking for advice about how they should build their car (Basically telling them how to build it) No one would need to use your shop correct? All people on the internet care about now days is flow numbers. But there is so much more to a port than that. Ask yourself this, when someone designs a port (Hand porting) and it flows x amount, How come when ever it gets digitized and cut (CNC'd) It moves less air, but would still make the same power? Because the shape is still there!
