90Q 20V header?

["Dupree, Jim" <dupree@alldata.com>]

Will a 20V header off a 90Q fit a 4KQ?
I may have a chance to get a factory header off a 90Quattro 20V and I
have an exhaust leak at the exhaust manifold on my 4000Q. I can make it
fit the exhaust system but will it fit in the engine compartment and
bolt up to the head. I have not seen it yet so I can't even guess. Would
it help or hurt low end torque? Of course I'll have to fix my wife's 4K
exhaust leaks first, maybe even replace the leaking heater core for her.
TIA
