I have access to the WIS (Mercedes Workshop information system) here at home, not sure if all the measurements are same for all the m177 engines but if so i could grab you the numbers from the mercedes WIS system for the c63s (only m177 vin i have lol)

EDIT: edited my message and deleted the file till i confirm the correct engine code list as the system gives you all the work sheets related to engine timing for ALL cars

So turns out i read your question wrong. my bad, honestly best way to find that i guess is to get your hands on a valve? not really the kind of info available even in the WIS. it just shows clearances in there thats about it.
these are the part numbers i found for my m177.
intake valve: A 177 050 00 00
Exhaust valve: A 177 050 43 00

Appreciate the part number,s but I meant how many mm diameter of the valve head is. Example M156 is 40mm intake, 34mm exhaust. Anyone have an idea on M177? I assume smaller given smaller bore size
anyhelp would be much appreciated
