Undy Dave was looking at some of my old race parts and crazy things I did. I suggest this to help take the load off one spot of the head and spread it out over a larger area. Get a small piece of flat plate and bolt it to the front of the head. Some heads have 3 bolt holes some have 2. 3 is better, 2 works better than one. Then you can bolt the torque bar to the plate. The shear factor is still the same but without possible damage to the corner of the head. Something to think about?
