[V8] V8 heads.....assembly

[DasWolfen at aol.com]

Both heads start as a common casting. The reason both heads have the same 
part number cast into them, that part number is the casting part number only, you 
will not find it in the ETKA. Common industry practice

Both are machined in exactly the same way. Common industry practice

Each is then assembled to fit the side it is intended for. Since Audi only 
services the heads as a sub-assembly and not a bare casting it only follows that 
the ETKA will show a different part number for each side. Common industry 
practice

 If you compare each head while its sitting on a bench you will see that for 
each location used for a sensor/bolt/stud/coolant pipe/hose adaptor there will 
be a matching machined/threaded/plugged point on the opposite end of the 
other head. Even the temp sensor locations are there but sealed with a threaded, 
removeable plug. Common industry practice

 If you wanted/needed to use a head on a side it wasnt intended for the only 
place you might have a problem is moving the coolant adaptor pipe. I suspect 
Audi put it in with an interference fit and some strong adhesive.
