Block Heater
The reason I ask is that we have cold winters here. My LS4 has higher mileage and some mornings I get a chatttery lifter. Hoping that a heater will help keep that from happening as I'm planning on driving this car until it dies.
As far as the lifter tick on start up, I don't know that a heater will do much to quiet them. It is usually the lack of oil, not the temperature, that would make them rattle. My cause was the o-ring on the oil pick-up tube. It had dried up and shrunk enough that it was like trying to drink through a straw with a hole in it. When parking, the engine would drop to idle and it would let the pressure drop enough that the lifters would not be full on start-up.

A quicker solution would be to cut the lower hose in the middle and install inline, similar to this but you will have to find one that fits the hose.

I have one I purchased for my Comp G as that gets driven more in the winter, I never got around to installing it, there is no pump it just looks like a heating element made by Kats but it should still warm the coolant. Block heater would work better in my opinion. I agree its doubtful it will help much with the lifters .Good luck, post back what you decide.
