Looking for the torque amount and procedure for exhaust manifold bolts on Champion GN1 aluminum heads. Did a search on here and general Google search and did not find anything.
 
Called Champion. 12 - 15 ft lbs if using factory bolts. Check and retighten after engine is warmed up a few times.
 
Studs are highly recommended over bolts.
ARP black oxide with 12pt nuts. For the extra long variants you can use set screws from fastenal.
