Manifold Question. Please help (1 Viewer)

[1970Cruiser]

I desperately need a new exhaust manifold for my 1970 F Engine. There is a 2f manifold on Ebay. Is it the same as the one I am replacing. Please help.

The header I bought was the same for the F and 2F. That may be an anternative for you. I think the heat riser would be the issue between manifolds.

The F and 2F intake/exhaust manifolds are NEARLY identical. They will not fit together, however, because the heat riser bolt pattern is different. 3 bolt for the F, 5 for the 2F. Also, the EGR systems differ a little bit.

If you replace with both a 2f intake and 2f exhaust manifolds then it should work AFAIK.
