If the threads hold, I am very surprised that the block deck is not distorted at such high torques. (125 ft-lbs)

Only a matter of time! :D

I bet such high torque levels do affect the crank centerlines, tho.

J, if those bolts were that loose, I suspect the gasket is either burned from the combustion chamber blast, blown, or the silicone burned away at a minimum.

If not, then I would start thinking about a crack in the head casting.

I am really cynical about retorquing after a head lifts...and I am more suspicious of a shim needing retorquing. Wonder if those magic studs were a bit stretchable?

I don't believe it is the shims that compressed and made the bolts/studs loose.

Time to pull that head and have a look, imo. frown

BTW, if they are aluminum heads, I wonder if steel gaskets are a good choice. Aluminum has more give than steel and might work better with a gasket that conforms rather than the head flexing?

Just wondering, no facts to support the thought.

Spend about four times as much money as you would if you figured it out before it blew?
