Just had to do that on a '97 Ford f-250 5.4L Dealer quoted $860, I was able to do it for ~$150 & solid days of aggrevation. You will want to replace other parts that you will never get to unless you remove the upper intake. So I spent a bit more on other things just to be safe.
About 450.00
parts and labor should run around $650
Intake manifold or exhaust? The complete job (parts and labor) is between $700-$900. depending on labor rates.

I have a 2002 Pontiac Gramd Am and its in the shop right now getting the Intake Manifold Gasket fixed on it! Its about $2000 with labor costs and everything! Rediculous! Its supposidly VERY common in these vehicles....They should do a re-call!
Sell your car.
I just had the intake manifold gasket replaced on my 96 century yesterday and my bill was $450 but my gasket was only leaking out. If its leaking into your oil it may be more.
$1000-$1500
arm & a leg

The gasket set is $55.00 The labor is $250.00
