<VV> compression test

[Bruce Alexander]

I have re- assembled my 64 110 engine after a "re-seal" Did a compression check. All but two cylinders looked Ok  ( within 10 lb. of 145 lb).  #'s 3 & 5 read 0. I backed off the valve adj. on those two cylinders, re-tested and got 160 & 175 lb.s can anyone tell me just what this might indicate?  such as bad rings, bad valves or what?
