No. The two low compression cylinders were also the one's that were misfiring. Also the one's with the leaky valves.
 
Water is a poor choice to leak test valves, it normally does not wet out the surfaces and with the surface tension it normally takes a pretty big hole to leak thru without pressure. Alcohol is a better choice. Bet those valves would gush with alcohol. If the head is still on the engine the alcohol will burn off evaporate much quicker but you still must worry about hydrostatic lock.
