[V8] 3.6L V8 engine needed

[Chris Brown]

  Hello, i have a 1990 Audi v8 3.6L  with a snapped belt and i was wondering if any good engines are available from members of this site.  I bought 1 already and took a chance, it was ok but it totally needs a valve job the heads are awful.
 So im looking for something a little better than that.  Im going to try Shokan and force five. My location is Connecticut. 
 Thanks  
  Chris
