@pittsburghracer yes that is a brand new ARP head bolt, just took it out of the box. I have a craftsman torque wrench and was using a Husky 6pt socket.
I’m not a lover of those bolts either as they have a very stupidly designed head that is way to shallow. No reason for it either. Of coarse I use studs on my junk because it’s race only but you should see what we go through getting the nuts on and off especially when we machine them for bigger valve springs.
