Default Fuel Injectors don’t seem seated

I’m in the middle heads, cam, exhaust on my 03.

I removed the injectors from the intake and several of pintle caps were broken. I bought new ones that are a new and improved ls1 design. Installed new o rings

Although the injector ls are in and the bolts went in fine, it doesn’t look like they are seated all the way, but i’m not experienced in this area. Anyone tell me if they are ok?

Did you lubricate the o-rings?

They look like they're seated past the bevel. Without an intake in front of me it's difficult to say whether or not it needs to go in any deeper especially if the rails are bolted down and the clips are all properly aligned.

I reckon that will work. The service manual just calls for clean engine oil.

The first pic doesn't look right, it looks like it's at an angle...could just be the picture. Stock everything, intake, injectors and rails?

I don't know how familiar your with installing injectors but sometimes it takes a little more effort then usually.

Yes stock ls6 intake, new orings. The Pintle Blocks are the only thing I am questioning, but they don't look at all like they interfere with the seating of the orings. I'll pull out and try again!
