are you asking because they rotate, or because you have no torque wrench?

i didn't torque mine, just buzzed them on with the impact gun and called it a day. it's been fine for 35,000 miles so far. IMO it's not very important unless you're dealing with bearings or gaskets.

so what was your psi at the gun which would make a reasonable guess why they didn't loosen on you!

If you don't get them tight enough, it can shear the pin on the cam.

haaa-i new you'd like that. i used the "little" snap-on 3/8 drive impact. iirc rating is 425 ft/lbs. i probably could have made bad things happen if i tried hard enough.

I don't think this is considered standard equipment. Just wack the boxed end wrench with a big hammer.

you can barrow a torque wrench from a local auto parts store.

When I did mine, I was able to use a curved jaw vise grip on the cam you are tightening.

I know it sounds scary, just do NOT clamp it on anything important, like a lobe (duh).

I clamped it on a non machined surface, and rested it on the edge of the head.

85 foot pounds is really not that tight, so the grips held with no problem and did not damage any surfaces involved.

There is a "special tool" mentioned in the service manual that holds the cams from turning, but of course I do not work at a dealer, and had no access to one.
