I just located a 86 Westy for my sister to replace her 78 Westy which is
getting old. She and her husband live in Lake Tahoe and they are ready
for a Camper with actual heat. The 86 has a typical head sealing
problem  where combustion gases are sometimes leaking into the coolant.
The heads are to be pulled and resealed, but I would like to find some
new heads in case they are needed. Is there more than one choice for new
heads and what are the considerations? What country of origin do people
recommend or otherwise? Are there other likely problems that may be
encountered?

TIA
