And your just asking to snap the studs off doing this. You are way past the yield point of the stud. Also DO NOT torque them hot or warm they must be fully cooled down.

i would do studs so you dont have any problems. when you torque bolts down they stretch thats why there is a torque spec on them, so you dont strech them too far and fatigue them. they will only put so much pressure down then they just stretch the bolt the further you go.

Cheap Head Gasket Fix
IMO...Those 4 words do not fit in one sentence together.

When you start talking about cheap fixes for headgaskets your asking for problems.

if your are gonna retorque your stock bolts, i think you need to at least back them out( brake loose) or even pull one at a time in the spyder web pattern and lube them to get a proper torque reading, i did mine to 125, i tried 135 and it felt sketchy, but when i get a job im get studs minimum, most of the bolts have some oil on them but some are bone dry and crusty.
