It could be normal, as the engine will rev higher warming up. However, you could have a vacuum leak, an unmetered air leak (air tube, air box), sticking idle air control valve also. Two minutes DOES seem a bit long for a 2002. Do you have any modifications on the car? This could affect strategy too (such as modified air intake...etc...)
It does have an exhaust leak and head gasket valve is leaking oil
Exhaust leaks at the exhaust manifold can cause issues, but if you're talking muffler/tailpipe, probably not. The head gasket / valve cover leaking oil cannot cause idle issues. Like Pvt-Public stated - it indeed isn't terribly a big deal at 1000 - 1200 RPM for a short time, but higher is definitely abnormal.
That's not 1 it is 1000 Rpm. How much above 1000? 1100, 1200 I would say no big deal, but if it is up at 1800 1900 you need to look at the cold idle circuit.
