Does anyone know of a diesel place that can fire ring heads in minnesota?

 

Not trying to put you down or anything but is there a reason you are fire ringing your heads? I have heard that they aren't good for normal driving and are only used in heavy drag racing vehicles and usually have to be replaced on a regular basis. They are more a of a safety measure than a normal thing. Of course I don't know much about them but just food for thought.

 

i have fifty thousand miles on my head and block no problems here
