Cam Install Question

Get to the arts and crafts store and purchase a small amount of clay. Put a strip or two across the valve reliefs and rotate the engine around a few times to activate the valves and depress the clay.
The valve lash should be correctly set when you do this.

If the clay looks like it is thin, cut it in half and measure with the below handy tool for how much clearance you have. Repeat if you move the cam around. (Advance or retard.)
