Default Do I Have a Intake Leak?

I've just put a take off LS6 intake on my car (from LS166NOVA) and the idle is slow to come down. It was not like this before. We have the idle set at 750 and when I'm coming to a stop the idle will drop to 1200 than 1000 and after a complete stop and a few seconds it will drop to 750 (this is the only reason I don't think its a intake leak). It makes for more braking to make a normal stop. I changed the IAC valve and I've done the idle relearn, and no change. Is it the intake or just gaskets? Need some help, please!
Thanks, Jason D <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

No, this is a stock internal motor so I had no reason to. But I was just asked the same question here at work.
