Head gasket and/or valve job not always kiss o' death

I've done head gaskets and valve jobs before on this car and an Alfa I owned and never had any problem with the bottom end. As to how this particular problem may have come about there are several different possibilities. This head came from another car and had supposedly "had a valve job". Possibly one or both valves have carbon buildup, one might be bent, or the "valve job" done wasn't done well. I don't yet know the answer to that, but will post when I do. 80% leak rate I take to mean that there is an 80% loss of pressure over a given time.
In my opinion if the bottom end of the an engine needs to be rebuilt every time you replace the head gasket or do anything with the head that tells me the engine is poor quality. Andrew, I've read other posts of yours on this subject and I don't know if you've just had some poor engines in the past or what, but I just don't buy an engine needing rebuilt just because you did some head work. I also replaced a head gasket on a Renault 12 engine and the bottom end was fine and these were not particularly robust engines.
Anyway, I'll update things after I get the valves right.
