Yes, there is supposed to bae valve clearance, here is how to check it. Also check the images below.
5. Inspect the valve clearance
a. Check only the valve indicated as shown. [No. 1 cylinder: TDC/Compression] measure the valve clearance
Using a thickness gauge, measure the clearance between the tappet shim and the base circle of camshaft.
Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting shim.
Valve clearance
Specification
Engine coolant temperature: 20°C (68°F)
Intake: 0.20 mm (0.0079 inch)
Exhaust: 0.28 mm (0.0110 inch)
Engine coolant temperature: 80°C (176°F)
Intake: 0.29 mm (0.0114 inch)
Exhaust: 0.34 mm (0.0134 inch)
Limit
Intake: 0.12 - 0.28 mm (0.0047 - 0.0110 inch)
Exhaust: 0.20 - 0.38 mm (0.0079 - 0.0150 inch)
b. Turn the crankshaft pulley one revolution (360°) and align the groove with timing mark "T" of the lower timing belt cover.
I. Recheck the valve clearance.
