Should I use same Torque on Bolts for my new Aluminum Intake Manifold as used on Factory Cast Iron Manifold? Thanks!

By the book, it is 23-28 ft-lbs for the intake manifold bolts for the Ford Y. The 1957 service manual does not specify aluminum or iron for the intake manifold bolts, but I will assume that value is for either. I typically just tighten the intake bolts in steps with a hand wrench or ratchet while paying particular attention to the tightening sequence. For the Ford FE, it’s 25-28 ft-lbs for an aluminum intake and 35 ft-lbs for an iron intake.

Thank You Ted. I will do it that way and finish with 25 foot lb pounds on the Torque wrench.
