are they rated at 43.5 psi like ours ,and if not what would be our equivalent in lbs
i read on some posts that they fit direct on our LT1s

You have to tell the PCM the injector's "flow constant". And that number has to be adjusted to reflect the actual fuel system operating pressure, if the fuel system pressure is not the same pressure the injector was flow rated at.
A 24#/HR SVO injector is flow rated at 2.7bar (39.15psi). If you put that injector in an LT1 with a STOCK fuel system pressure of 3.0bar (43.5psi), the injector will flow about 5% higher than it is rated.
(43.5 / 39.15) ^0.5 = (1.111) ^0.5 = 1.0541
The 24# SVO needs an injector constant of 24 X 1.0541 = 25.298#/HR
