Sorry I was after exhaust manifold specs.

My blue "Motor's Auto Repair Manual 1971" lists 12-16 ft.lbs for 302, 18-24 ft.lbs for 351 exhaust manifold (for years 1969-1971) with clean and lightly lubricated threads. Did not see anything on sequence/specific order.

Did it say that these torque settings are for manifolds with no gaskets used ( as they were when originally installed new at factory) or with gasket as I'm doing?

I placed this enquiry on another site and 2 others said torque up to 30ft.lbs.Just worried about over torque as can cause cracking of manifold.

It does not say if it is with or without gasket.

I think most guys here have headers. I might be able to get a torque wrench on a couple of the bolts. I use wrenches on mine.
