I have a blown 84 vg30 engine and am looking for an engine to replace it. I was wondering if there are any problems with dropping in an 89 maxima engine.

I'm aware of needing a spacer for the pulleys and the dipstick location but is there anything other then that?

Have you seen this?

Yes.

"These include the pre-24 Valve Maximas(89?)"

This is my problem. Is there any reason an 89 would not work.

Is the 89 Maxima engine a 24 valve dohc? If not, it will work. The point they are making is the Maxima VG30E will work, the redesigned 90+ Maxima VG30DE will not.
