There has been lots of talk recently about performance upgrades for the Stovebolt's. My Dad always told me the guys that we serious about making some power used Wayne 12 port heads and also some guys bought stuff from McGurk. I know that the 12 port heads are like gold. Just curious if anyone has a Stovebolt with some of this vintage stuff that is up and running? I know that I have seen pictures of guys running on the salt flats using the 12 port heads.
