I replaced the 4 hose bellows and now need to put the manifold back on and torque the 4 bolts down . I snapped one bolt already and was lucky to be able to get it out. can someone olease give me the torque for these bolts? omc stern drive,3.8liter, v6 gmc.1985

Thanks Steve
 
I just "snug" 'em because cast iron is brittle.

but they should be studs,
bolts do not belong there.
the original nuts are locknuts, so the torque doesn't have to be high.

standard torque for 3/8" coarse is 32-36 lb. ft. clean and dry.
I'd stay down around 25 and then retorque to 25 after a couple of runs
