So theres no way to gain a couple of cc's at all?

 

AFR says that every .010 milled is 3 CCs

 

yes but the missing point is all you are doing is taking a slice of .010 off the chamber at the very bottom you are in no way altering its design or shape that would occur from grinding it out.

 

Have you placed a call to AFR? They might have a CNC program for your head to regrind the chamber.

 

Milling it negatively affects the flow. Not sure how much taking some material out around the knot hurts things. I wouldn't try to go 7 or even 5 but a couple ccs isnt that much. On a NA car, you wouldn't be doing it anyway.

 

Afr said that they dont offer enlarging the chamber there but i might could get somone who knows alot about cylinder heads to do it. He said that up to 13cc could be achieved by enlarging it, they just cany do it.

 

Well that is good news for you. Now you need to find someone knowledgeable to do it.

 

but the guy didnt seem to know how bad it would affect the flow.

 

If you got someone who knows what they are doing it may not affect the flow hardly at all. Maybe even improve it. These guys may not come cheap either and are probably backed up in work. I'm talking about guys like Curtis Boggs, Larry Meaux etc.
