Bolts? Studs?

Totally agree if you mean that all head gaskets need to be torqued down more then stock torque which I believe was 55-60??? I do think that most rebuilds are going for 70 or more??

Anyway - my point was that studs make it easier to get even higher torque then factory bolts - and the more torque the better!

I have wondered if you can torque down a composite gasket too much? to a point that the crush rings expand too much into the coolant and oil passages? Don't think metal head gaskets have the same issue.

Only real way to tell is to put one in - torque to 90 then run for a few years and take apart??
