I am doing the TBSS intake swap onto L92 heads on my LQ4. The intake came with new intake manifold bolts. I am looking at these L92 bolts, and my old truck intake bolts and the older truck bolts have rubber isolators under the heads. The washer area is a little bigger than the new bolts also. I am just wondering if these new bolts were supposed to have the isolators on them or not. Here are some pics about what I am talking about. Also, does anyone have a part number for these new bolts, I lost one. Do you think I could just use one of the older truck intake bolts as a substitute?

TBSS Intake = cathedral ports

L92 Heads = rectangular ports...

Sorry, I guess I assumed it was a TBSS intake based on what I'd heard. It is a 2009 truck intake with the square ports. It is significantly bigger than the old 2004 truck intake I took off. It's rectangle ports on rectangle ports, everything lines up perfectly. The issue is just whether or not I can use the old bolts, and if I need to swap over the rubber isolators, thanks.

Im not sure on that. I just looked at my TBSS intake and the bolts that came with it dont have the rubbers either and the 6.0 intake I have does but they dont seem to come off the bolt.

Cool, thanks, I think I'll just pull the rubber piece off one of the old bolts and use it. I can just grind some lip off of the washer are so it fits.

Have you tried pulling up the schematics for an 09' truck intake assembly off gmpartsdirect.com to see if they show rubber washers on the assembly? I think that might answer your question but don't have time to look lol
