run high octane gas + some kind of fuel treatment
good tune up
fresh oil change
and drive the car for a while before you have it tested

Not recommending anything here just thinking back.

try some stp octane booster maybe?
take a look around at autozone they have a whole shalf of this kind of thing

One local smog shop that does many test without failures, they make eveyone set in there cars and keep them running until it's time to smog them and then they drive onto the test-machine without letting the cars cool down. They think the cars have to be fully warmed up to be clean enough to pass? Keep in mind your 1980 car is not held to the same standards as the newer cars are so you will probably not have a problem as long as the engine is in good tune and the engine is not worn out and burning oil.

Do you have the emissions equip still installed and working? How about the cats? Is your engine stock or modified?
I think a stock healthy 200 with everything working and well tuned will pass the smogs easily. Go to a shop with exhaust testers and you'll see what comes up. In a shop you can adjust things to improve the result. If you have problems you can try playing with timing and idle speed for example. Here '80 cars get only tested at idle; I got mine thru by retarding basic timing down to close to zero and by adjusting the idle speed close to highest allowed, which is 1000 rpm here.

The current smog check (at least here around San Diego) has them check the car under load. The drive wheels of the car are put on rollers to put a"load" on the car, then they run the rpm's up and check the emissions while the engine is under load. One thing I did was increase the air pressure in the rear tires for the test ( to reduce the tire surface contact on the rollers). Kind of like pumping up a bike tire to make it coast better. Rides kind of stiff, but rolls better. Every little bit helps! I've seen additives at Kragen that guarantee you'll pass but I've never used them. If you are in doubt about the car passing the smog test, I'd recommend getting a "pre-test" done and have them tweak it in if need it. Reason being that pretests are not sent to DMV, so if your car fails miserably it wont be labeled a gross polluter (which would make you have to go to test only station. $$ instead of $). Good luck! Of course the other option is to get a 1975 or earlier car and skip the smog altogether!

i have a stock motor. everything is new except for the egr. the cat is broken in so that won't be a problem. the timing is set to 10 degrees, the idle is set to 800 in park. all vacuum lines are hooked up. the hood finally closes with ease. i tweaked it right after putting in hood pins. good thing i am getting a new hood. just fixed a tranny line blow out. runs great. fully warmed up it is 180 degrees. i have used that "gaurenteed to pass" stuff and it worked to get my mom's car to pass smog with a blown head gasket and cracked block. i will inflate the tires and change the oil. i put that smog stuff in so i will put octane booster in it when i refill the tank. i am really nervous because i have worked my butt off to get it to this point.
