I had a new set of head and check the pushrod length when originally installed. pattern was dead center and narrow. In about 2000 mile the guides were shot and it was smoking. I had all the guides replaced and the maching shot could not see why the guides were worn out. The wear was not oblong. It was the whole guide ruling out geometry right? I was inspecting all the parts putting it back to gether and found this. (see pic)
looks like the rocker was misalligned and contacting the valve. Would this cause the guide wear? All my specs are in my signature below
