In fact, it fits all OHC 4-cyl Volvo engines, except for the ones with 16-valve heads (AQ171, which is DOHC)

I have used the very same Sierra manifold in an AQ140A and had no problems whatsoever. Of course, you can always buy the original Volvo manifold at premium price (it lists for $729.75 ), and that is BIG bucks!!
