Or for people that prefer not to do frequent head gasket jobs?

Yea, yea I heard about the select few PS guys that run stock bolts but they also have a secret recipe of sorts. How many bolts did they break off to figure that one out?

They aren't not blowing because of the torque # or strength of the bolts, I'll tell you that much. It's all in the machining, fire rings, and gasket.

At 14mm and a 625, wouldn't the cast iron threads give long before the studs would stretch?

Just curious.
