OK, Bought a 07 with a couple problems today.

She will never notice a thing probably. I plan on disabling AFM with HPTuners. Just have not done it yet. It is a 2014 with 130K so i need to do it soonish i spose.

Got the replacement engine tore down for the gaskets and seals im replacing.
Overall not bad looking on the inside, but the heads do have a little sludge built up in them. It's not hard and baked, just gooey.
Need to flip it on its side to clean that out so none of it gets into the engine pita, but i can't leave it in there.
The oil pan has some gunk in the bottom like the heads, but i did not see any sparkly stuff at all and that's a big relief!

You may want to Google info about those 5364 heads. I believe they have some issues, so if your current engine has 821/823 heads, use those instead

I actually did check on them as i had never seen them.
Are you thinking the 823 heads that are known to crack if they have a casting mark that looks like a battery?
As far as i can find reading 5364 heads are as good as the other two casting number heads you normally find on 6.2L engines.

Oh, here’s a bad idea. Rebuild the 6.2 and return the 5.3 for the core deposit

Though of that. Have a 5.3 here and asked if that would work. Big NOPE!
Good try though
