RS2 manifold, 20vt variations?

[Ken Keith]

I think I read that the intake and exhaust positions are reversed 
between the urS4 motor and the '91 200q20vt.  This is part or all of 
the reason why AAN swaps are more difficult than 3B ones, I 
believe.

I've also seen reference to people putting RS2 manifolds, and 
turbos, on both versions of the 20vt motor.

Is this correct?  The RS2 exhaust manifold fits on either motor, 
even tho' it is on the opposite side?

Thanks,

Ken
