If you mean the 11mm nuts, 12 ft. lbs. Check them once in awhile because they tend to loosen up unless you used blue Lok-Tite on them. If you have the long 11mm nuts a Snap-On 1/4" drive swivel socket size 7/16" (or .4375"; 11mm nuts are .4331"), a long 1/4"extension, and small torque wrench with 3/8 to 1/4 adapter will do the trick easily with the carburetors off of the manifolds.
"Glue" the manifold gaskets to the manifold and put a LIBERAL coating of Chap-Stik (yeah, Chap-Stik) on the cylinder head side of the gasket; that way the gasket won't stick to the head the next time you take the manifolds off (it's a bitch to scrape parts of a stuck gasket off the head surface in the engine compartment).
If your heads/manifolds are match-ported take a small and very sharp Xacto knife and carefully trim the glued-on gasket to fit the manifold ports.
Put the manifolds over the studs, put on lock washers and nuts finger tight; make sure the manifold isn't hung up on the engine tin, etc.
Torque each side to 5 ft/lbs. Then torque each side to 10 ft lbs. Then torque each side to 12 ft lbs. Then one more time at 12 ft lbs and you're good to go.
Then do the other manifold the same way.
