Aluminum Exhaust Manifolds
 

Wanted to make sure on the correct bolt torque for mounting Revolution Marine Exhaust manifolds. I have not seen these in long while as I forgot the torque specs of the manifolds and risers. I have customer who has a new set to install on his big block. These seem to be almost like Eddie Marine exhaust manifolds. I was thinking torque specs of 25 ft lbs for both riser to manifold and manifold to cyc head. Is this correct ? THX

Anyone or how about an educated guess or throw a number out to make me feel better that I least got a reply. just messin. I'll give RM a call to see what they recommended.

3/8 stainless bolt 25 ft lb is fine.
