there's also the difference between n-heptane or gasoline flow ratings, which is a small difference, but it does make a difference.
depending on the level of ethanol in your fuel, you may have to account for that in your injector flow constant as well, since the stoich afr variable (if it exists) in EE is unknown.
then there's your offset table.
you should make sure before you buy injectors that a proper datasheet including a proper offset table is available.
30lb injectors are a bit big for a stock-ish engine, but will give you some growing room.
why dont you confirm this is the issue by doing a homemade flow bench? disable the ignition coil for safety then, hang the rails and put a container under each injector.
keep fire extinguisher handy
first just run the fuel pump to check for leakage. then just crank the thing until you get a good sampling. if you have one injector flowing more than the rest, you'll see it real quick in the jar.
you should also check fuel pressure and the other basics while you're in there
