This is the rear head for a 42 knucklehead that we are doing. Check out the rear exhaust stud. Somebody welded the shaft to the rocker tab. My dad wont admit to it, but I think we all know it was him. Whoever did this sub standard repair wasn't too concerned with ever taking the head apart.
Here is what it looks like after a little bit of grinding.
Ta da! The shaft is out. This head is messed up.
