Sorry I should have wrote that up better, I am currently running the green tops in a LS2 fuel rail. So I have the electrical adapters and they fit on the fuel rail side. I am concerned about the intake side for the rings because they currently fit an LS2 mani.

I got the LS1/LS2 conversion kit from Katech, and the wiring adapters from FAST. -P

Gotcha, then you just need LS1 o-rings for the manifold side of the injectors.

I don't remember how many valley bolts you need, I'm thinking maybe 10 also, but if you don't change them all out, you'll crack the lower manifold because there is not enough clearance with the stock bolts. If you are missing one, a good hardware store might carry something similar.
