More info is always better. Is the low idle rough or just unusually low? are you getting any CEL's?

You said that the headgasket and timing belt were recently done. I'd double check the timing to be 100% sure that it's correct. Another thing that lots of people forget to do is to bleed the coolant system which can cause an air bubble that freaks out the coolant temp sensor and throws off the fuel trims leading to rough/low idle
