I have 4 head studs, how should I torque them? My engine builder used 4 head studs for some reason. The front and back on both sides in the middle row. I think it might be a good idea to reuse these, putting l92 heads on my ls2.
Any ideas how to torque them?
Should I just torque the rest as normal and then use the arp head stud torque rating for the studs?
Any advantage to reusing them?
I remember he mentioned something about using a helicoil on one of the heads, this might have something to do with that.

Step one, kick the engine builder (cough) square in the nuts...
Step two, get a complete set of matching studs and torque per manufacturer's specs
with their suggested thread lubricant.
I can understand wanting to use a stud on a thread repair, but at that point he should have advised on switching ALL the fasteners to match.
There is no way to get even clamp loads with different fasteners.
