Injectors too small for 331?

i have a chp 331 pro street stroker, ported performer rpm intake, ported rpm performer heads, 1 5/8" equal length headers, o/r h-pipe, 1.6 rockers, 274hr camshaft, ect. 190 in-tank fuel pump.

i just bought 24# injectors and matching pro-m. ive seen people running 24's and 30's.

with a combo like this should i be safe with the 24's at 40 psi? or should i run them a little higher? its a street car, and will probably never see more then 5500 rpm if that.

just want to be safe with this engine after my last experience. thanks for the input. i know there is a guy running a really similar combo to me but i cant find his name for anything.

id really like to.

im going to do an easy driving break-in. i know its a big arguement on how you can do it. im going 100 miles, oil change, 500 miles, oil change, 1000 miles, oil change. then again at 3k. easy shifts, no higher then 2500 rpm.

the thing with the dyno-tune is there isint really any places around here that im comfortable going to. they are a few hours north or south of me. there is one shop about an hour north, but everytime i hear feedback its misleading. well see, i definately want everything to be done right though.

thanks for the input
