I think you'll be fine with the stock injectors. You MAY have to bump the fuel pressure a couple of pounds which would require an adjustable regulator if you don't have one.
It would be nice to have some kind of an a/f meter. I believe Edelbrock and others sell them. You'd know right where you were, whether lean or rich and could adjust your fuel pressure accordingly. Another option is to get the car on a chassis dyno and try a couple of different fuel pressure/timing combos. You'd know immediately what was the best. They usually only cost $75 or so for a couple or three runs.
Bottom line, you should be fine with the current combo on a mild small block. As (if) you continue to add power, the a/f meter, etc. become more important.
