How long will it take to put a head gasket in a 2000 ford taurus?

Just need to know cuz my husband is workin on one for someone else so he can charge them the right price

Call any Ford dealership, ask for the maintenance department, and then ask what the "flat rate" estimate is for labor. They have a book that gives "flat rate" times for doing various tasks. This is not to say that your husband can do it in that amount of time, but it is a ballpark figure.

I did a 96 Taurus (3.0 V6) in 3 days. I wasn't able to disconnect the exhaust pipes from the manifolds, so I had trouble wrestling them into place once I had the heads re-installed. That probably cost me half a day of work.
