Other than coming up 2 short, I don't know why not.
The LS system is operated at 58psi, {4 bar}. So, the 3 bar rated injs will have a higher pph.
What size are the v sicks injs?
Depending on how the LS fuel rails are spaced, you may have to change the rail mount height.
The various LS intakes will have different rail configs.
