How can I tell the difference visually between a OM617.912 NA head (small gp holes) and a 952 turbo head?
I've got one here that got set aside and not sure what it came from.

If it still has the Precombustion Chambers in it the Turbo precombustion Chambers have rounded tips I believe the Non-turbo ones have flat tips.

It also could be there is a part number on the Head somewhere.

there were three HP ratings on the OM616...

1) Not much power
2) Even less power
3) Not nearly enough power!! 240D w/auto

Anyone that thinks a 240D is slow drives too fast.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

The non turbo (OM617) heads ended up with the improved pre-chambers in the end
