"Ticking" sound from engine

Gents,
I've had a nagging exhaust leak for some time, but yesterday, I changed my oil and while I had my car in the air, I wanted to see if I could figure out where the "ticking" sound was coming from (the ticking that I thought was the exhaust leak)

With the top engine cover off, I tried to pinpoint exactly where the sound was coming from and it sounds like it's on both sides of the engine right where the intake manifold tubes connect.

Now, I'm gonna show my engine illiteracy here, but I know only the term "lifters". I believe we have "hydraulic" lifters, but I don't exactly know what that means. Do these "tick"? The exhaust leak "tick" gets louder with RPM and I didn't figure out where it was just from a visual/listening inspection.

The one by the intake manifold didn't sound like an exhaust leak though and has me a little nervous.

I'm at 70k on a '00 base.
