Is anyone using them? If so, how much have you been able to flat or angle mill them? Mine currently have 56cc chambers and I would like to take them down to 48-49cc's. Trick flow says I might run into the valve seats and will have to have a valve job done. They have 2.15 intake and 1.60 exhaust valves.

I ran into another problem. Had the chambers cc'd this morning and they are 62cc's. Will flat milling a head change the flow numbers? What about angle milling? I don't know if I am going to be able to get down to 48cc chambers or not. I should know in a few hours.
