First thing to look at would be the simplest. Small exhaust leaks sometimes tick and can sound like there is a problem with the engine. Check for that first, around where your manifolds bolt to your heads, and also underneath. A good way to listen for them is to have someone pit their hand over the tailpipe, and this will cause the exhaust to build back pressure in the system, if there is a leak you will begin to hear it even at idle.
Other than that, you might have a slight lifter noise, it doesn't seem common being on something that new though
