Re: Intake & exhaust manifold torque
Second try:
Why are you suggesting brass nuts? Ford used steel, the same nuts as for the cylinder head.

Re: Intake & exhaust manifold torque
Could your muffler not have a passive fit on the manifold? I had trouble with mine seating and pulling open the #4 exhaust port.

Re: Intake & exhaust manifold torque
Lady said if her body was a car she would trade it in for a new one, cause
every time she sneezed her radiator leaked and her exhaust backfired.

Re: Intake & exhaust manifold torque
If you were going to use steel nuts, you should use anti-seize on the threads to prevent the fasteners from corroding together (c.f. the very common situation of the intake and exhaust having become fused due to corroded steel bolts). And then you're back to the original problem of excessive torque, because 45 ft-lbs on lubricated threads is again probably too much for this application.

I leave the 2 bolts holding the intake manifold to the exhaust manifold loose while tightening it down the first time and then snug them up too. Some day I'll put a torque wrench on them and check the torque value of my snugs.
