says it comes out of an early 80's pontiac with a 2.8. IIRC the only early 80's pontiac with a 2.8 was the firebird.

 

From what I can see those will *not* bolt to our cars. Look at the angle on the bolt holes.. one pair are off at a 45 degree angle, the next pair are off at the opposite 45 degree angle.. our flanges are straight up and down bolt holes...

And if pontiac made a version of the citation, there goes your "it has to be a firebird" theory right out the window...

 

Not off a bird. Maybe a Fiero?

 

Those aren't 2.8 headers- Those are off of a 90* V6, not a 60* v6.
They way you can tell right off the bat is the center primary doesn't favor the right side like it does on the 60- v6.

 

Those look completely different from the hedman headers I have on my 2.8.

 

if I'm right 80 and 81 had 3.8L motors and that is early 80's. would they fit a buick 3.8 in a 85 cutlass though. coulld always tell my wife her manifolds are leaking and I'm just putting the same thing in.
