The tick is normal but should not be that loud.

Some ticking is 'normal' as they age. There is no easy adjustment. You have to shim the clearance.
At a minimum, I would pull the valve cover and just have a look at the cams. Might be be some build up of "crud". Sometimes a thicker oil in summer will help with the ticking especially on high mileage engines.

What year is your LS and how many miles?

I used to hear that tick when i ran 10w30 briefly and it disappeared when I switched back to 5w. That was many miles ago though. Since I did the cam seals I can hear it again but that's only if I have the hood open.
