Can you use LS1 Injectors on LS3 Intake?

Swapping over to a LS3 top end with a stock LS3 intake. Can I use the LS1 injectors on the LS3 intake?? I have the stock LS3 fuel rail.

All the searches I have found are for LS3 injectors in a LS1.. not the other way around...

Yes, you'll just need to get the spacers for your fuel rails in order to fit the taller injectors. You're using EV1 injectors in place of the shorter EV6's.
