I bought a used engine for my car.The problem is it isn't the year engine he told me it was.

If you tell me what size engine you have and what year engine size make and model the other engine is i can tell you if its a match?

I have info that says your engine in your riveria for that car will work for 1995-1997 the park ave 1995-1997 so a 1990 park ave says it wont work.Atleast according to my info thats a long block with no intake or exhaust manifolds.

I think you should interchange it immediately, but if they are not replacing it then leave it. Tell the size or specification you want I can recommend you a place to buy good quality used engine at reasonable price. For your help, I am suggesting one site i.e. http://allusedparts.com/engine.html that has large inventory and offers wide options to make a choice. However, no need to depend only on this, there are many more options out there as well. Just suggest what you are looking for.
