Dodge Repair: 1991 Dodge Van, head gasket, water leaks

Question
My 91' Van tries to stall when slowing down below 15mph. Just did tune up- but didn't help. Compression check showed one cylinder about 12% lower than all others and water leaks out tail pipe. It also idles rough and seems to have a miss. No codes when I checked only 55 came up, which they said meant no codes. Could it be valve lash off, or head gasket? The stalling started out of the blue, it ran okay until then.
Thanks,
Anne
