I am running a set of these, but am not sold these are the way to go.
Yes, there is a surprising amount of stretch in the stock head studs. It
made me nervous torquing the head to see the wrench swing so far to
achieve the torque I was shooting for. I got used to it... Then the ARP
studs. The torque wrench does not swing nearly as far as it does with
stock studs.
I have to wonder, was the stretch designed into engine/head assembly? As
the engine goes through a heat cycle and things start moving, the ARP
studs are not allowing much of anything to happen with the head/block.
No doubt there is some expanding going on with the stock studs...
Which goes back to the directions provided with the ARP studs. They say
torque to something less than published torque. When I followed those
directions, my head gasket leaked.
I really never had an issue with stock studs. I am wondering if the ARP
studs are helping me or hurting me...
