Start with 1/4 turn. Put the engine at TDC on cylinder #1 and adjust both intake and exhaust, turn the engine 90 degrees and adjust both for the next cylinder in the firing order (#3), and continue 90 degree rotations, adjusting both valves in the cylinder until you run the firing order. Review your geometry and kame sure the rocker tip is relatively centered on the valve stem. Now drive the car how you will run it normally. If they need more adjustment, simply add another 1/4 or 1/2 turn without rotating the engine. Each time you make a change review the geometry.
