Default torque for intake bolts?

I've searched the tech forum for 10 minutes and couldn't find anything other than a pdf of torque specs which (hilariously) didn't have the intake manifold specs in foot lbs, and I only have my cheap torque wrench here that shows ft lbs only, not inch lbs.

I would also recommend cleaning the threads of the bolts of any old residual thread locking compound and double checking that the bolt holes are clear/clean. Those bolts are very long and very thin and will twist or torque fairly easily. I like to use a drop or two of blue Loc-Tite too.

See at the bottom of the link, they show the proper sequence. No 8 and 9 are rather difficult to reach

ft. lb. = in. lb. / 12 but you should really be using an inch-pound torque wrench since the torque level you'll be applying is at the low end of a foot-pound torque wrench where its accuracy is low. In fact, typical foot-pound torque wrench readings usually start at 10 ft. lb. so you probably can't even set it to the correct torque.
