The very best way to set your valves is to turn the engine using a rachet by hand... turn it in very small increments near the Exh. opening measuring the lash as you move the engine. You will see a point where you measure the MAX. lash, remember this point (maybe jot down the degree off the balancer and what the lash is) when you move it further in the rotation your lash will decrease. The point at which you measure your MAX lash is where you want to check it, as stated earlier some cam profiles are unique and require a different approach. When you have the Int. point of movement figured out, simply use the same method on the Exh. of course at the point the valve has pasted max lift and is closing. I've spent a fair amount of time trying to show my son how to properly (at least in my mind) set valves...he's starting to get the idea of the importance of selecting the proper time to check the lash.
