I was checking rocker arm adjustment on a new motor, and found very little clearance between the rocker arm and the locking nut when the valve is in the closed position. I may be could get a piece of paper between the nut and rocker arm!!!!!!! The valve is closed so rocker should not travel upward any more??????? The rocker arms are 1.7 ratio, checked with a 1.73 rocker and this gives me alot more clearance. But changing ratios may throw off geometry???????? What gain could be expected if any going to a 1.73 ratio.

I’m having the same issue. I will try to create another thread but the forum wants me to comment on other threads before it will allow me to post anything. Thank you.
