head studs

i have to agree torque to what they say on a DD, but on a comp engine with high boost they will not hold the head down enough. i lifted the head on mine and blew the fire rings in 2 cylinders way out of place went back with a new fire ring gasket torqued to 150 this time no issues since. but keep in mind this engine does run between 80 and 95 psi down the track depending on the tune i run. also with everyone i deal with in the aftermarket that builds engines they all do the same on race engines so arp may know a lot on it but street credit and real world proof means more than computer designs and controlled testing, atleast to me anyways.
