If you hear a ticking from the area where the block and head meet it's more than likely a ticking valve or several ticking valves. adjust the backlash and see what happens is the best advice I can give. If you've got some time and want to dissassemble the engine, easy valve measurement without the proper tools can be done with some silly putty smoothed on the dome of the piston. Reinstall the head and turn the crank BY HAND very slowly one full engine cycle. take the head off and check the putty. If it's gone way through the putty, adjust the valve or valves back. Again, these is a very elementary method, but could get you by until you can do it properly.
it can somewhat sound like a tick from in the car. asp. on a honda, but when you pop the hood it's distinct. check your valves. honda's tick. period. unless you are a machinist like my brother, who can get damn precise.
