Briggs says on a cold engine, .005 on intake & .007 on exhaust. Wider on exhaust to ensure you don't burn a valve.
For the aluminum the intake valve clearance is .005 to .007 inches. exhaust valve clearance is .007 to .009 inches. Cast iron is - intake valve is .007 to .009. inches exhaust valve is .017 to .019 inches
I assume valve clearance and it is 0.004".
