You're  saying that to run with unleaded gas was an original design goal?  
Is  
there any documentation to back up that  statement?

Ron - I think you are mincing words a bit. The Corvair was designed to run  
on available fuel of the 50s, A byproduct of the engine design -aluminum  
heads with valve-seat inserts, means leaded fuel is not a requirement for  
valve seat protection, as it is for the 50's cast-iron heads, pre-induction  
hardened. The Corvair can run leaded fuel - or not. It is part of the design, 
 but not the reason for it. Most of the rest of the engine is happier  
without lead -providing sufficient octane is provided. Like several folks, I  
have scraped the 1/8" thick gray goo from the oil pans or engines run in  the 
60s and 70s. Lead contaminates more than just ground water - it leaves  
deposits on valves, plugs and most other areas it  touches.
