Default rough idle

I have developed a rough idle after replacing the cylinder head on my 2000 cherokee. It seems to idle about halfway over the 500 rpm hash on the tach, which seems normal. It acts like a have a big cam, kinda lumpy. It otherwise runs great, and I've had no stalling problems or rpm flares. Any common issues other than vacuum leaks and such? It's a little better with the a/c on and idling around 750 rpm....
