Generation IV External Engine - 60lb LS2 injectors

I am so confused about all these injectors types, spacers and connectors.

I have a LS2 C6 2005 Vette.
I need 60lb injectors.

What connector do I need (EV?) ?
Are these the same as LS1 and LS6 ?
Can I find bolt on ones or just with spacers/o-rings ?
Cheapest place to buy them ?

Thanks,
Mihai

These are LS2 injectors that are 57lb/hr. So they will absolutely drop in place of your stock LS2 injectors. No more confusion.....
