What torque is recommended for the nuts holding the manifold clamps on the engine?

My '27 has bolts. Is this original?

Thanks Mark. I had purchased an intake/exhaust manifold installation tool from Lang's. I checked a friend's '24 and the tool would have worked perfectly with the studs, but my '27 has the bolts (OK, if you want to be really technical - capscrews). I eventually wound up making my own tool that would work with the bolts. It worked well, if I may say so myself. I'll bet the engine was lying on it's side when the folks at Ford's installed the manifolds at the factory!

I think it's easy to install the manifolds without any special tools - I just install the exhaust manifold loosely first with only the outer clamps oriented up/down. Then I install the intake manifold with the two inner clamps in their intended direction and screw then almost tight. Then I can twist the outer clamps right and tighten them all, no extra hands needed. Should work both for bolts and studs? Will check.

I have done this many times. 30 ft lbs feels right to me. I have tried 35 but, it felt a little scary. Retorque as mentioned.

Do what Jack D suggests but be careful. You'll feel bad if you break or strip a stud or bolt. If it leaks a bit tighten a bit more.

Works for me.
Easy.

Roger's way works for me too. Don't try it with the exhaust pipe connected, then you will have a real fight on your hands.

I do it the same way Roger described. No issues.
