You use a 2x8 rafter, you have to use the next size bigger which is a 2x10. If it a 12/12 pitch, the plumbcut would be about 10-5/8", therefore sticking lower than the 9-1/2" 2x10. Some towns would want a 2x12 there because they don't want any of the rafter plumbcut below the bottom of the ridge.
Are you getting permits and also do you have a set of plans?
