I am just curious as to how "new" this will make my Toyota V6 3.0 engine. It currently has around 160,000 miles on it. Will it make it last a lot longer now? (Obviously it would if it had gone bad, but I am asking if by putting a new one on there, if it would make the engine a lot "newer" now or not)
why?

BTW, What are the usual things that go bad in an engine that make it ready to buy a new one or rebuild it??

a new head gasket will make a better seal than the old one did. as far as making the engine "new"...not quite. all the waer on the bottom end, valve guides etc will still be the same...

Realistically, putting a new head gasket on a car is of no value unless the gasket is already leaking.
Some of the maintenance that is sometimes done while the head is removed, has some preventative maintenance merit. Like cleaning the carbon off of the cylinder head, milling the head to make it flat again (if it has started to warp).
In theory, if you had replaced a gasket just before it started to leak, you would have saved some wear and tear on the engine. But really, this is pretty much never done unless the head is off because of an engine rebuild or the gasket is leaking.
If you want to do some preventative engine maintenance to make the engine last longer, you could replace the oil pump. Reduced oil pressure is the beginning of the end for an engine. Though bearing wear is one cause of reduced oil pressure (the extra clearance reduces the pressure), the oil pump itself wears with time.
BTW, the cause of most head gasket failures is an overheated engine. So keeping the radiator and cooling system clean and well functioning is better preventative maintenance than replacing the gasket.

TRUCK OR CAR ??????????????
Toyota has started to actually recall most 88-93 V6 Trucks and 4Runners to replace the head gaskets under warranty. In the past they has a Special Policy Adjustment to correct any problems. If you have had yours done already you will not be notified again to have the gaskets replaced. Those of you that purchased the newer trucks with the 3.4 V6 engine you may experience a leak of red fluid from the left or right head gasket, this is repaired under warranty and has been corrected in production in 96.
IF NOT A TRUCK THEN REPLACING THE HEAD GASKET AS STATED ABOVE WILL SEAL THE HEAD BUT THERE ARE MANY OTHER THINGS THAT CAN GO WRONG, IE: THE LOWER END...........

A head gasket is only a small part of an engine rebuild. Simply replacing the head gasket with out getting the heads looked at (which may need a head job/valve job).
Other things that wear include the piston rings, rod bearings, and main bearings.
How much longer your engine lasts will depend on the conditions of the above mentioned items.

Cylinder head gasket no don't touch it.
If your cylinder head gasket is leaking into water your coolant i.e. Your water should look white and creamy.
If your head gasket has gone and is leaking into the internal structure of your engine you should feel a slight pressure over your oil filler point.
Check your compression per cylinder.
I suspect you do not know much about car engines, but
'cheaply ' buy a 'cheap' compression gauge this measures the pressure inside each cylinder.
To use this gauge you will need to remove the spark plugs from all cylinders, put the pressure gauge over the first sparkplug hole, crank the engine till you hit full pressure and measure the reading.
Repeat this per cylinder, you will then be able to ascertain if the engine needs to be rebuilt.

Head gasket is leaking compression gases into water jacket, pressurising it and driving water out the radiator overflow. This is during around town driving, Go out on highways at high speed and the pressure can rise high enough that the overflow can't handle it fast enough and the pressure can blow out a core plug on the block and suddenly dump all your coolant. let the problem last long enough and your valves can become toast and your radiator clogged You need a new head gasket and the head should be checked for true. It might require planing at an auto machine shop. Don't rule out the possibility of cracked head or block. Your suspicion may be correct that the bloke who sold you the car didn't tell you everything.

Replacing the head gasket will make the engine run better and prevent the engine from having a early failure, but it will not make the engine, bearings, cam, pistons, rings, etc last any longer.

Excepting replacing a damaged on it will make absolutely no difference whatsoever
I have been driving for over 40 years and in all that time have only ever had to replace 2 blown head gaskets
If it ain't broke, Don't fix it

replacing the head gasket makes no differance to the wear factor of the engine you have just cured a fault , that made it run bad
