Should i only replace head gaskets or complete head gasket assembly on Ford Taurus?

Complete head gasket assembly.But first get the head gasket problem confirmed.Don't just replace any part,without confirmation.

If you go to any good parts store (Autozone, Advance, etc...) buy a head gasket set - it includes every gasket you need to do job.
Head bolts and head gaskets. Let's see, you will need a lower and upper intake set as well. These head gaskets usually blew because bad fan relays caused the gaskets to blow and warped the heads. This problem of head gasket blowing is very much noticed on many other Ford Taurus model,because Ford used cheap oil pressure switches that leaked as well.

So get this possibilities checked.This will help.Thanks.
