GMC YUKON GAS PROBLEM

1999 GMC Yukon • 224,000 miles

Blew a head gasket. Replaced gasket and installed 2 new heads. Now that its all put together starts but idles very slow and rough. Was wondering what could be causing this. Didn't have any ideling problems prior

Check for vacuum leaks. Valves adjusted correctly?
