Rafee is selling a pair of converted 110 hp heads that have an strange  

combustion chamber shape. Has anyone seen heads with a CC like this? They

look to be factory and not modified. Please ignore the 4 carb
conversion...just the

combustion chamber .

 

Any comments or thoughts?

It looks to me like the machinist ground the step back, away from the plug.

Note that Rafee's description mentions that they have been modified for low

compression so perhaps he can see evidence that's not visible in the photos.
