I also experienced a ticking after installing heads, roller rockers, and aluminum valve covers. The mechanic said the ticking was the rocker clicking back and forth and the valve covers were aluminum and were letting the sound out. It wasn't that bad anyways. I definately wasn't harder to start though...
