You should be fine using standard torque for the size bolts that you have. If I had it handy, I would surely post it for you.

 

Thanks Ramjet, but I stole the specs off of Edelbrock's site. Im figuring that the manifold that they sell would take the same torque as my Offy.

 

its 45 ft lbs for cast manifold but i'm pretty sure the aluminum manifolds require a different setting.

 

As far as I know, it's the same torque. The idea is to stretch the bolt, not mash the manifold. I used the standard numbers on my Edelbrock after a few people laughed and explained it to me.

 

Aluminuim I wouldn't torque mor than 25

 

Aluminum torque specs will be less than cast iron.
