Which company does re-chambering of stock banshee heads and what does it cost? I've got to top end my banshee and there are some pits in one of the chambers. I figured I'd get the head milled and rechambered to take out the pits and bump up compression but I don't know who does it.

 

You can try www.dirtfiendracing.com they mill and reshape the domes for $105.00 dollars on a computer CNC machine they come out perfect and equal in both combustion chambers, unlike others that just use a manual mill.
