Valve gone?

[95 gsturbo]

I have a low compression ratio: 2 of them 1:20 the other two were at 1:50 regular is 1:80 right? My car doesn't accelerate as fast, car starts up slow, chugs its way up, and my motor has still the knocking sound, I don't believe it is lifters, because it does tick, but it sounds too hard of a tick, the knocking or ticking gets faster as i accelerate? How can I solve this is there a FAQ out there that will guide me step by step to checking my engine valves, or other things that may be bad?

wtf where did you learn to put sentences together what is 1:50,1:80.1:20? i think you are trying to tell us that the compression is low in two of your cylinders,and that the compression is 120?. please explain what you are trying to ask in understandable english.

ooops sorry not too much of an expert on this sort of thing, but yes I have very low compression on two of my cylinders 120 and on the other two is 150. The rest is right...
