How much boost have you ran through stock Hbolts over torqued?

i ran 60psi boost on stock bolts torqued to 125 for close to a year no issues.

put studs in , one at a time without romoving head, torqued to 140, been running that for about 2 years with twins, seen as much as 75psi, no issues. Original head gasket with 232000m on it

i'm with swole, torque in small increments, and be patient
