I installed ARP studs, tightened to the specs someone posted on this site. It went in 5 different increments all the way up to 210ft lbs. The next morning I rechecked all of the studs to 210ft lbs and then began putting the motor back together. I got it started last night and just finished my coolant flush this morning. Do I need to re-torque the studs now or after I drive it for 500 miles or am I good to go and shouldn't worry about it?

 

I purchased ARP studs and installed them using the provided instructions. Nowhere on the instructions do they indicate that a re-torque is needed. Good thing too because it is a hassle to get to them.

 

I've used this set of studs 3 times and never had to retorque them.
