New member, long time lurker

Hey guys, glad to be here!

I have had my 07 lbz for about 9 years now and have read countless threads on here, but never took the time to join or post.

I've neglected my truck for the past year or more while using it to pull equipment and unfortunately have quite a bit of damage to address and will be attempting the job myself.
I have cracked heads, broken manifolds and a shot turbo.
I have a pretty good idea of what parts I'm buying but any suggestions are welcome!
And I've never done anything beyond a t case pump run on a diesel so I'll be needing a lot of direction on the work.
Thanks!

Welcome.

Start looking for some head gaskets as apparently the ones you'll want are hard to find or have long lead times.

Otherwise get ahold of the venders here to get pricing of the parts you'll need. They help support the site so it's the least we can do

Are the OEM grade C gaskets the standard still?

I read somewhere that your supposed to measure head protrusion, not just run the grade C. But that's the first I've heard.

GM switched to the "Gold" gaskets and they are failing at a higher rate then they used to. I'd try and stick to wave-stopper if you can

Ideally, yes, you measure first and base the gaskets on the protrusion. Many will use grade C so they can order ahead of time and.have everything ready for when they pull the heads off. But to do it correctly you measure it first

Wow, that's definitely great information.
Thank you!

You should measure piston protrusion for optimal results. Somewhere there is a chart.

LML - Piston protrusion/head gasket...

Getting ready to start engine assembly as soon as it gets back from the shop. I have a couple questions concerning piston protrusion and quench. The block was decked once already, and is bored .040 over. Split a piston in it a little over a year ago. Back then I put in Fingers pistons (17.5:1...

Awesome!
Is there a list of vendors and their sites? I'm not having any luck finding one

Look on the main forum page and scroll down to the vendor section. Brad or Josh can help you.

The wave stopper gaskets or Victor Reinz are the go to gaskets.

If you're not touching the block or bottom end of the motor, you don't need to measure piston protrusion. You can just order the same grade of gaskets GM shipped the motor with. There are tabs that stick out past the heads with holes in them, and the location of the holes indicates which grade of head gasket it is. Just remember each side can be a different grade.

That said, if you're pulling the heads off and aren't in a hurry, it never hurts to measure protrusion yourself, then order the correct gaskets.

You sure you have cracked heads? It's very rare to see a cracked head on an LBZ.

Yeah, one of them is cracked above a valve where the coolant is leaking into the exhaust.
I'm thinking the turbo vein failure caused high egts when pulling heavy, but not sure.
The heads are off, found a small piece of debris made its way into one cylinder and damaged a piston, broke a ring and there's gouges at the top of the cylinder... At 225k Its looking like I'll be dropping in a new complete stock engine.
