Did they give you the compression numbers? If so post them here.
I would suggest that you do yourself a favor and have an independent rotary shop do another compression test. It will cost you a few bucks but you want to make sure you need an engine rebuild or replacement before spending the several thousand dollars that will cost.
Or you can do a basic compression test yourself. Go to Aaron Cakes site for instructions on how to do a simple test:

Low compression could be caused by carbon buildup on the apex seals. Try running a can of Seafoam through the gas tank, then get a second opinion on the compression. Good luck...

here are the numbers: R-1: 5.8, 6.1, 5.6 at 260rpms. R-2: 5.9, 6.1, 6.2 at 261rpms. i also tried sea foam, the car wouldnt start back up after i put it in the gas, i had about 10 gallons of gas in the tank and while it was turning over white smoke was coming from the exhaust.
Perhaps you put too much sea foam in the tank? Try filling the tank and cleaning or replacing the plugs before attempting to start again. Then do a deflooding routine. With those compression numbers, you need to ensure that you don't shut the engine down cold to avoid flooding.
