Anyone have a how to thread for the head gaskets I'm debating if I want to attempt it but not sure I've been quoted 4500 bucks to do the head gaskets and just dont have that kind of money to put into it.

You can do it, just take your time! If you decide to part with it let me know.
I think I'm going to try and attempt it I'm gonna try and figure out by Monday on what to do. Heard that it's best to buy the thickest gasket that's offered I know the head bolts have to be replaced I'm not planning on upping the power any so ill prob just use regular oem head bolts instead of the studs.

I've been looking at the truck more I think its got a bad injector cup along with an injector cause its got a injector tick. Really wondering if its not the headgaskets and just a bad injector cup and injector. Hmm

Don't take this the wrong way, but that sounds like real wishful thinking. I certainly would like to hope for your sake it's just an injector cup, but it sounds like it's a head gasket.
