Hey everybody, I haven't been on here for awhile and hope you all are doing great. I have a question about the head gaskets on my 2010 GMC Yukon Denali 6.2. My question is are the gaskets supposed to be like 3 sheets riveted together or did I get bamboozled by rockauto? It's my first time in one of these engines lol.

Which head gaskets did you purchase?

They are probably MLS (multi layer steel?). And yes, they are riveted together. I've only used the Felpro version of them.
There's a marking that says "Front". Make sure that's towards the front end of the engine.

Oh ok cool! This is the first time I've ever seen gaskets like this so wanted to ask before I go forward with the assembly. All I can say is you all and this site are true life savers to guys like me, thank you so much. I sure miss my small blocks lol
they make these MLS gaskets for sbc too. I have some in my 406 made by cosmetic.
the exhaust gaskets on your kit should be MLS too. they single layer stuff isn't as good.

You may want to consider replacing the head bolts with ARP bolts while you are in there. Do the same, and even more important, for the exhaust manifold bolts.
