lower intake manifold torque specs

Anyone have the torque specs for the intake manifold to the heads and if possible also the intake to the baffle or whatever that thing is under there. Thanks.

4.6 romeo engine.

All the bolts (to engine and to heads) have the same torque specs. First do the engine mounting bolts, then the bolts to the head, torque them in 2 stages:
Stage 1 - 18lb-in
Satge 2 - 89lb-in

yeah they all bolt to the heads, 9 bolts overall and then 2 where the main radiator hose goes. are those specs for the 5.4 ( i don't even think that would make a difference) Oh an can you verify ft in? When i pulled them off they were in really tight, but 90 lb in is like 7 ft lbs. I used a breaker bar for most of em.

You're right, it's not really to the engine. What I meant are the bolts along the center part of the manifold, upper to lower manifold bolts.

Correct "lb-in" , straight from "Ford Technical Service Manual".
8 bolts - upper to lower manifold.
9 bolts to heads and 2 on thermostat.

Just checked again 4.6 and 5.4 are same.
