Can i fit 4age 16v exhaust manifold to a 20v?

About to do a new 2 1/4 mandrel bent system on the AW and have access to a set of 16V extractors.
(i can also supply these bends at good prices incl donuts pm for details)

So will they fit?

pretty sure they are very different as any headers i've seen can only ever be used for one or the other.

well.....
to fit a 20v header to a 16v you slot the holes.....
so to fit a 16v header to a 20v, logic dictates you slot the other way....

but logic also says its not the best idea...
what 20v have you got?
i cant recall the size of the 16v exhaust ports off hand.
but the vlack top ports are the biggest of them all. so fitting a 16v header wouldnt be too flash....
cant remember if the ST ports are smaller than the 16v or not....
