The only reason everyone puts studs in after a head gasket blows is becasue if you gotta pull the heads off anyway, you might as well upgrade.
What would you define as "big tunes"? I ran Edge on Extreme and Hot Unlock for years, Xtreme Race from IDP as a daily driver for a little while, and now SRL from Gear Head as a daily driver. However, Edge detuned when cold and now I don't hit the loud pedal unless it is up to temp.

just a thought
These are "Torque to yeild" bolts, one time use, as in they stretch, adding more torque would most likely induce failure of the head gasket and/or the bolts.
Before tuning, HAVE GAUGES, after tuning, DON'T hit the loud pedal before it is at operating temperature.
