Manifold Flange Thickness (1 Viewer)

Does anyone have a pair of manifolds off their 2f that they can measure the thickness of? I'm going to 3fe manifolds with a 2f intake and need to know what the difference in thickness is, thanks!

Edit- Any pics of 62's exhaust systems would be great as well, still haven't figured out how I want to go from two 1.5" pipes to one 2.25".

Will that work? I thought the 3FE stuff only worked on 3FE heads and the 2F stuff only worked on 2F heads

I know Trollhole runs them on his 86 2f, and they may fit older 2f heads as well.

"Do you know if those headers would work with an older 2f head without the extra bolts?"
Yes. You said it, the extra bolts are extras. 83-earlier 2Fs have the 6 12mm bolts, but not the 6 extra 10mm bolts. So the manifolds are compatible in either direction.
