Question about cutting valve guides 4 seals

Wyrmrider said
what size now
I like the 031 better than the 000 but nothing wrong with 9/16
use biggest that will fot in your inner spring
get viton seals

Inner spring ID is .807
.562 seal OD is .665
Differance of .142
Divide by 2. = .071. Clearance

Is that enough?

I know the .531s have plenty of clearance but if the .562 will work I would like to save some guide metal.
