At least these comedians are calling your busted wing a turkey leg or turkey wing...could have been worse. I broke the ball off of the ball socket in my left shoulder. So,if your surgeon suggests surgery for repair to soft tissue damage do not think twice about it. In the long run you will be ahead. The shoulder is the most complex joint in your body. Find the best shoulder specialist you can, it is not an easy thing to fix properly. It is a very specialized set of skills. You should appreciate this knowing what you do about head porting. Not just anyone with a flow bench and cutters can do magical things in performance. Same applies for your shoulder and it healing with the fewest complications. Do not ignore your doctor's and therapists advice Mike. You will heal faster following their experienced wisdom.
That is an incredible piece of engineering in that head. I wonder how much difference it would make and driving four valves instead of two adds to the head's friction and requires the oiling system to be top notch. Wonder if a twist on the design with roller rockers could net even more improvements?
