Quick question: Need torque specs for plenum to intake manifold

Hi all.

1991, 3.1L, "T" motor.

I need the torque specs for the plenum to intake manifold screws.

(These are the M6x50mm flange screws with the steel sleeves and rubber grommets/bushings)

My model specific-Chilton's offers no data on this particular part.

Thanks.

Torque specs are available at autozone.com, repair guides, just sign up.
