Under NHRA rules, you can mill the head, but they specify minimum combustion chamber volume. Stock valves with any valve job, no other modifications to the head, like epoxy or porting. I am planning on a 12 bolt with 5.13 gears, the Lakewood traction bars that replace the lower control arms. I have to run a 3 speed, 230's weren't available with a 4 speed. Has to be correct model carburetor, securely fastened.
