on a stock banshee head.

.020 = ??cc domes
.030 =
.040 =
.050 =

what is the most i can have milled off without rechambering the domes? and what will my dome size be? thanks in advance.

 

Rechambering or correcting your squish band is exactly what you want to do to increase performance! The stock head has a lousy cut and milling alone wont do much. Send your head to be cut/rechambered right by a good shop.

 

Ant suggestions? How about cost?
