What do you torque an IH head down to that has a copper head gasket and .105 fire rings? I changed from bolts to studs and I can not get it to seal at 185 ft/lbs.

Have you called and asked the stud manufacturer?

I make them and sell them, do not over torque them! If you torque over about 180 FP on a 9/16 stud you have little reserve before it yields. Use ARP Ultratorque lube to get the best clamping force. I tested different lubes and found it to be the best by about 10% on clamping force.

I am not good at posting links, should practice.
The easiest is to go to my website, Fanta-Machine.com , then click on "Tractor pullers and engine builders", that will take you to a page that has pointers to some of the videos. The site needs updating as we have other items besides studs.

Please don't do that. Both ARP and the ones we make here yield at the equivalent of 230 - 240 FP, you have little left over for reserve.
