Heads up unlimited raising on the river

Actually all you guys that said always go down to the felt no matter what are wrong.

If it's obvious that you and your opponent have the same hand, and there isn't a cap on rake, then the correct play is to call once you have realized that it will be a chop.

Of course, if there isn't a rake or it is already capped, THEN you should go down to the felt.
