Your book is different than what mine says.

Mine says .010" clearance at normal operating temp.

at .0010 ( 1 thou. ) would seem a little tight.

.....................................................................

In comparison, D-10 and D-12 Operators Manual:

Engine at Normal Operating Temp.

Intake Valves at .009", Exhaust Valves at .015" HOT
