How do you adjust the valves on a 1974 amc 304 engine?

To adjust the valves on a 1974 AMC 304 engine, first ensure the engine is cold. Remove the valve covers and turn the engine to align the timing mark for the number one cylinder at top dead center (TDC) on the compression stroke. Using a feeler gauge, adjust the intake and exhaust valves to the specified clearance (typically around 0.008 inches for intake and 0.010 inches for exhaust) by loosening the lock nut and turning the adjusting screw. After adjustments, recheck the clearance and reinstall the valve covers.
