No apology necessary haha, don't worry about it

A reason for head bolts loosening off could be detonation. At 18psi on an upgraded turbo this could be possible?

SIDEWINDER: I guess, I owe you an appology: you are correct. 75 for the bolts and 80 for the nuts.

ARP definitely lists a torque specification. If I remember correctly it is 82. And if you cant remember what to torque them to, look at the piece of paper included in the box when you buy them. It tells you exactly what to torque them to. NOTE: If you use oil to lube the threads the torque setting must be much higher, this could be why some people claim to have torqued in the 100+ range. This is also from the paper included in the ARP box.
