When I did mine, I found the EGR pipe blocked with soot at the intake manifold. Also, the pipe on the bottom of the air cleaner tha mates up with the hose to the back of the passenger sode valve cover was also blocked. Don't forget the clean the small orifice in the idle air bypass area and cold start injector. I had to use my trouble light probe, with a really sharp point, to push out the gunk.

Check the groove on the heads under the intake ports for carbon deposits.

I used a media blaster to clean my intake manifold both inside and out. It looks really great now, at least the parts that I can see.
