Default What size injectors do I need?

I just purchased a 94 gt with the following work done to the engine:
-Trickflow upper and lower intake
-Edelbrock Performer heads
-Crower 15511 cam
-1.6 roller rockers
-Hooker shorty headers
-MAC catback exhaust
-MAC CAI
-65mm throttlebody
-190lph fuel pump

The previous owner did all the work to the car. It is using 24lb injectors right now and a bbk adjustable fpr running at 42psi. I think this seems like a little much and I have a set of 19lb injectors sitting around. I just don't want to put them on and run the risk of leaning out the engine. Does it need the 24's or would I be fine putting the 19's in? I really don't want to spend the money on an AEM UEGO to tune it once and then not use the wideband again.

Thanks

yes a 190 will be fine with any rpm one 24`s as long as you have a good working regulator.
