Check your maf? If the noise is coming from the head then take off the timing chain guide.

it could idle better with an sr swap but thats my opinion



seriously though what kind of noise does it make. what have you checked and what can we rule out.

like he said check the maf.

could be a vaccuum leak.

are you getting fuel.

hows the spark.

are all your connections good i.e. injector clips.

is it a misfire?

Well your mechanic is wrong because theses motors do not have belts they have chains and I highly doubt that your cam timing just hopped a few teeth your valves would be hitting when you crank it. So that's not the problem. No as far as ignition timing that's is one thing I would check also the vac lines right under the throttle body one goes to the intake mani. Also look at the connection at the maf make sure nothing is shorting.
