Through one twist of fate or another...I've ended up having the VCs off my truck since the initial H11 head stud install 3 times now.
The amount of movement some of the stud nuts required during torque #2, left me with the indelible impression that hot retorques will be a thing I believe in from here forward 1000%. Most of the stud nuts, took 1/2 to 3/4 a turn.....some took a nearly a whole turn (Snap On recently calibrated tq wrench)....:wtf:
To the point of this thread...I had the VCs off in-conjunction with troubleshooting another issue, and couldn't resist the urge to pop a torque wrench on there and see if things had shifted yet again...to my surprise...4 nuts took greater than a 1/8 turn. Torque #3 complete. Yay. :flush:
Well...the VCs are about to come off again.....is torque #4 too much of a good thing? It seems intuitive...just like any other bolt on the truck, to verify torque spec......nothing loose.....but with the H11 tool steel tensile strength vs. the block vs. practical application of real world experience vs. ???..
Factory forged motor, 98K when springed/studded/injector'd/turbo'd...now at 102K. Forgot to add-Studs were done one by one, initially torqued to 95, then two steps up to a final tq of 135.
Would definitely appreciate responses from folks that have had HG failure, are in the 12s/550+ hp, running 50 psi setups, etc...
TIA
