What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Anyone have any experience with Cometic head gaskets?
I see they have a nice selection of different thicknesses with the mls type.

I'm running Cometics. Nice stuff. Summit had the thickness I wanted in stock.

Guy at the machine shop told me they were gtg as well.
did you just put on plain, or use some copper sealer spray?

And i finally got the engine mounts off of the frame.
driver side was toast!

I had no idea, but it might explain the random clunk when taking off.

I also had no idea that they were captured bolts... lol

Get the Hummer H2 solid rubber mounts, they never fail. Edit: nvm, I see you went with them already.

my brother did my engine. He dusted the copper spray on the gaskets because I had 200k mile short block. I don't think it's necessary but I don't think it hurts

I did H3 mounts. Bolt on like stock. No complaints in the 30 miles I've used them
