Intake manifold torque

Aren't factory bolts TTY? They stretch by design.

Also, as you've probably sean or heard about, too much torque on a magnum intake can crack a block so the legend goes. Doesn't take much force on a magnum due to the angle of the bolts to seal it up. Don't gorilla arm it...

Regardless, we did ours per the 12fp you did and it's still running fine, no leaks. Possible your torque wrench is out of whack? If you're using a FP TW, instead of a IP TW, the torque will be suspect.

Just thinking out loud.

Not in my opinion they are not. The only TTY bolts I ever messed with was on a GM. You would tighten to a set LB torque, then turn an addition degree setting.
These start out in in lbs. but end at 12 ft. lbs.

I agree on over torque. Im going back at 12 lbs. (same as before) but Im adding the sealer Mbaird suggested.

Thanks to everyone for their input.
