Put something in, if it doesn't sound right, swap it out. Never be afraid to experiment! I can't tell you how many times I've used values that were "close" to the schematic (and some nowhere even close), for both caps and resistors.
I also experiment with different values, but I assumed there must be an important reason for specifying an unusual value such as 604r. Not sure how to use 2 resistors in series on this layout, there isn't much space to add another resistor.
