Can  someone expound upon what GM did with these?  

Mine is factory  installed, been sitting for years, never apart....   RY smog 
code -  correct to protecto plate.    Pings like none other at this point (  
as would well be imagined, will get a good cleanup etc).      Sure runs nice 
though!!!
Sooo I'm guessing smog heads, offset crank gear  for 140 PG etc.   Anything 
else?

Geoff,
Really hard to say for sure. We just don't have any reliable info on these  
engines from GM. Best info says that the heads were standard issue with  
stainless steel exhaust tubes. But that is about all known for sure. They  probably 
followed the same assembly equipment as the non-AIR 140 hp  engines.
