1997 Honda Accord LX - No engine compression

I just purchased this car and was told that it just needed a new head. I purchased a used head, installed it, but now there is no compression in the car. There was -0- compression in all four cylinders. Pistons and sleeves are good. Any help out there! Thanks!

Based on your statement that now there is no compression, implies that there was compression before. So, timing may be off, or you have a bad head with bad valves or you need to adjust the valves. Keep us advised what you find.
