been doing some reading, lots of people say you need to retorque the studs but i dug around in the manual from arp and they say it isnt necessary. i plan to check my valve lash tomorrow so that would be the time if im going to. i installed the studs with arp's lube and over torqued them by 12ft/lbs per arp's recommendation.

thoughts?

I installed mine just like you did and then adjusted valve lash. Then put about a dozen heat cycles on them...then retorque once. When I retorqued I didn't loosen them just hit em with the torque wrench. Only a few of them moved just the slightest...the rest were good. Then I rechecked valve lash again and they were all good. I don't plan on retorquing again...they are good to go.

just got a call back from arp. they said to not retorque unless the gasket mfg specifically called for it

checked the lash, it was all tight but still in spec. couple thou max change so i guess thats just the head lifting a bit as the power is hit?

What do you think about a little cam, lifter, push-rod, rocker arm & top of the valve stem wear? Of course you get some of that back with valve & seat wear.
I followed ARP's instructions to the letter and haven't looked back.
