Are most of the 24# injectors (ford and chevy) the same? Do they interchange? Thanks

Yes, however, the TPI injectors are only 22#, the LT1s are 24#. You will run a little rich, unless you know how to tune your chip, or have someone make you one.

How much difference?
If I go from 22# to 24#, How much difference can there be? My motor will not be stock anymore, I'm building it now. I'm just trying to do my homework. Thanks for the replys.

Not very much if you keep the fpr at 43.5psi. You will only notice a difference at idle, you probably won't even feel the difference anyway.
