I personaly changed R10 to 47K, because it won´t work with 120k at all.
Then I changed r5-r8 to total 50ohms,
to drive 16ohm headphones too, is it allright with 50ohm?

It will work alright with 47 kohm, too.

Using 50 Ohms output load, is no problem.
And for 16 Ohms headphones this can even give better, more current pushing

For 32 Ohms HP:s (and higher impedances)I would not change the original value for R5,6,7,8
It is carefully tuned to give very good result using these values
at 12 VDC operation
And HeadPhones 32 Ohm or higher.
