The Stovebolt Site Forums The Shop Area Engine Shop Installing Intake and Exhaust Manifolds, '54 235

I would tighten them both at the same time. There is allot of play on the manifold(s) to head, so if you tighten just those manifolds you stand a good chance that the exhaust to intake joint will be misaligned. Hand tighten all three connection sequentially first, then torque to spec. Honestly, I didn’t have the right tools to be able to torque all of the fasteners so on a few, I took my best guess.
