On my 2.1 WBX, one head is an AMC brand the other isn't. The AMC head
is on the passenger side.

If one could determine which head has been replaced, can this narrow
down which side of
the engine to focus on?
Or is a possible issue like a combustion leak between head and
cylinder(s) still a 50/50 split between work done on newer head or
parts on the older head and cylinder wearing out?
