Its hard to remember,but I THINK 305's came w/ 19 lb/hr injectors,L98's had 24 lb/hr and LT1's have 26 lb/hr.
Unless you have alot of work done to your 305,I would stick w/ the stock size injectors but buy an AFPR like you had mentioned.

305tpi's -- 19lb/hr
350tpi's -- 22lb/hr
Are you looking through junkyards? All the JY's around here won't let you rip things like that off, they want to sell the whole thing complete...
EDIT: Are you burning your own chip? If not, bigger injectors aren't going to be the proper way to improve fueling. It'll either be lean at high RPM and good and idle/part throttle or rich at idle/part throttle and okay at high RPM. I bet it'd work, just not all that well.
