Valve lashes only need to be done when the valve piston clearance inside the engine is off. Factory service manuals will list the appropriate clearance levels for the 2003 Honda Accord.
I want to know the number for the valve lash adjustment.

Yes, but you need to find out why they are knocking. May just need a valve lash adjustment.
the manual say's that both valves are .13mm
They are adjusted with shims. As you do not have a shim kit for this purpose and it would be expensive for you to buy one, take your Accord to a Honda dealer or mechanic who has a shim kit and have them adjust to valve lash. This is really not a DIY repair due to how it is done.
0.15mm intake 0.25mm exhaust
.004 in. intake and exhaust
From the Honda spec book: Intake = .002", Exhaust .002"
Hopefully just a valve lash adjustment.
The valve lash specifications for a 2008 Honda Foreman (specifically the TRX500) are generally .005 inches (0.127 mm) for both the intake and exhaust valves when the engine is cold. It's important to check the specifications in the owner's manual or a service manual for your specific model to ensure accuracy. Regularly checking and adjusting valve lash can help maintain optimal engine performance.
The '89 Prelude Si has a Dual Overhead Cam (DOHC). The valve lash for the DOHC is INTAKE: 0.08 TO 0.12 mm EXHAUST: 0.16 TO 0.22mm.
