Before you condemn it (or do too much work) try a little old trick ... stick a desertspoonfull (about 10 cc) of lightish oil - redex used to be great for this - in the suspect pots and leave overnight, then do the compression test again. If it improves drastically you may have a sticky piston ring or two, in which case repeating the exercise 4-5 times may well free them up and restore full compression.

HTH

Agree with what you say but, if my engine was at that stage, I wouldn't be relying on it   :'(

Why was the head gasket changed previously? Could it have had a belt or tensioner failure in the past?
