Default Valve stem clearance in bronze guide

Hi, mates.
What can be the clearance of inlet and exhaust valve stems in bronze guides?
I saw in workshop manual the std clearance with std guides:
in - 0.03mm
ex - 0.055mm
It seems too large especially on exhaust valves. Isn't it?
And with the bronze guides the same clearances will be true or they can be some smaller?

Exhaust has most likely got more clearance as they are hotter and expand more.
I would say the clearance is the same with BRONZE guides.
