How long does it take to replace a head gasket

[240sxluv]

i have a 1989 240sx fastback with the 2.4L SOHC and the head gasket is blown how long would it take to replace a head gasket if a professional is doing it

If a professional is doing it, it shouldn't take more than a day. Last summer I replaced the head gasket in my girlfriend's Avenger and it took me like 6 hours (my first time doing it, without ever seeing whats under the hood of an Avenger before.)
