Well I've bought head gaskets from Volvo, Renault and pattern parts (3rd 
party) and they're all basically identical. The reason the DeLorean has 
problems with head gaskets is the electrics controlling the cooling 
fans, and in our experience water pump thermostats are failing quite 
regularly now. There's nothing wrong with the head gaskes in a D as long 
as you don't cook the beggar. Change your rad fan switch, re-crimp the 
connectors and heat-shrink them. Check the relay for the fans and make 
sure the fan fail socket is clean and you have good fat jumper wires 
with clean connectors. Lastly make sure the fans work properly and the 
blades are attached. Change your water pump thermostat and make sure the 
coolant bottle cap holds pressure (recently had one in that didn't and 
boiled before reaching temperature). This lot adds up to $50 (if that) 
and will save several times that if the head gasket(s) do ever go.

Rubbish! The old ones come out square because they're 20 years old! I've 
stripped several pre 83 Volvo 760's and they're all the same.
