Re: rocker adjustment
The stock pedistal stuff should come to 20ftlbs withing 1/2 turn from zero. If not adjust pedistal height. THis should give you about .040 preload (depression) of the plunger. A little more, a little less, no sweat. You just don't want to bottom out the plunger, and have the valve unseat. Or set the rocker to such funny geometery that it causes guide wear and seal failure.
FWIW - all valves adjusted using:
Intake valve starts to close = adjust Exhaust valve
Exhaust valve starts to open = adjust Intake valve
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
