Rocker arm stud torque

Does anybody know what the torque should be for rocker arm studs on an aluminum head. The spec i have is 60 ft/lbs but that is for iron heads.
Thanks

I didn't look in my service manual, because that would be for iron heads. My "Chevrolet Power" book says 50 ft lbs, for either iron or aluminum heads. It goes on to say to use sealant in iron and oil in aluminum. *I* would use sealant in aluminum, on the intakes, if they are through drilled into the intake ports as mine are.

RACE ON!!!

Though I drive an '88 Vette I also have a GM Shop Manual for the '85 Vette; the torque spec for rocker arm studs is indeed 50 lb-ft.

'96 Factory Service Manual calls for 50 lb-ft. I always put blue LocTite on them when installing.
