Head bolts = 105lbs. If you have had the block decked, you might want to verify the bolts don't bottom in the holes. Mine did and I had to use head bolt washers to keep the bolts from bottoming in the holes. Mopar Performance sells a valve lash adjustment chart decal that you can stick under the hood. Makes it nice and simple and you don't miss any. Intake manifold bolts = 45lbs.

Thanks for the specs. I was aware of them bottoming out and check All is good so far.

if you are using a magnum intake on magnum heads then the intake bolt torque is 12 nm. almost nothing

Magnum intake torquing pattern. front to rear pass side is 10-6-2-4-7-11. Drivers side front to rear 9-5-1-3-8-12. torque bolts 1-4 in the sequence in 12 inch lb increments to 72 inch lbs. Then the remaining bolts to 72 inch lbs(in sequence). Check that ALL are at 72 inch lbs. If not tighten them up to 72 in sequence. Then tighten ALL bolts to 144 inch lbs in sequence & recheck.

This this method apply tojust the stock intake or an afermarket i have a air Gap manifold??
It would apply to both as torque specs are about the particular bolt being used to get it to the right amount of stretch & the 12 ft lbs would be for the stock type bolts & not sure if the angle(vertical) affects this also.
