Your adjustment instructions are correct....Yeah, I wasnt talking about a 1/4 or one turn past 24 lbs. I was saying do zero lash, and then torque to 24 lbs, and from zero lash to 24lbs ft lbs should happen with a 1/4 to 1 full turn.
There are rocker shims available to help,,, I believe the kit I have has 3 different sizes included.

What I purchased were some roller tip rockers which reduce or eliminate most of the valve guide wear... I found these at Lunati....
