Head gasket woes

Replacing head gasket, water flowing out exhaust, white smoke, milky oil over heat 😞 trail tech temp sensor saved my motor.. hopefully

Looking at this head gasket.. can you see any visible indications of failure?
Only maybe 6hrs max on gasket.

Going to lap/re surface head, install new Kms head studs, cometic head gasket, maybe some copper spray..

IMO, the pics aren't good enough to see any issues...

I think it was my lack of assembly knowledge.. combination of me not bleeding cooling system properly and no re tq head bolts after heat cycle 🙂

New head studs and gaskets are here, going to resurface head and try again

I've read on here in multiple posts that OEM is the only way to go for head gaskets..people have had issues with the cometic...including me.

But what is the issues? Is it just installation or the actual material.. I’m going to take my chances and do the steps I listed, and hope for the best.. I have used cometic gaskets before on a race motor back in the day, we’ll on cars.. and they are a reputable company.. I hope I got a good one! And I am installing new kms was ARP head studs
