Engine Head gasket blown? Twin turbo Cobra

[Monkeybutt2000]

You don't need to re-torque head bolts after final torque down.
Honestly with a boosted engine I would have gone with ARP studs, but that's me.

I wonder where this came from. I mean,millions of cars are manufactured every year and you don't bring them back for a re-torque.

Gaskets have improved for this reason.
