Most of the ticking caused by Fram filters is because of the nitrile ADBV, but your Tough Guard uses a silicone ADBV so it should be okay. The oil should also be okay.
Have you isolated the noise to the front bank, or just the top of the engine? I can't remember if our injectors are visible - if they aren't buried under the intake manifold, unplug one at a time and see if the noise will go away.
