My point was, as you raise in-cylinder pressures, you put more force on the bolts. The clamping force (look up the UTS) of stock head bolts isn't very high compared to even 425 head studs. That leads to a head lifting and a gasket failing. In my experience, going too much past that point on stock bolts can result in a head gasket failure.

Right, so why wouldn't you want to address that failure point when you start throwing more at it?
It sounds like you're trying to say timing doesn't play a role in in-cylinder pressures and head gasket failures...
To each their own. I'm not trying to argue.
