If You have a Lawn Mower start it up and let it idle. Come back 2 minutes later and put you Hand on the Cylinder head. And, that Lawn Mower has the Fan/cooling system working.

I think if I ran the Engine for 2 minutes with no coolant I would not get away with it.
The Aluminum Head is more prone to warping even in normal circumstances then the Iron Heads are. And, more prone to have problems when abused.

Anyway best of luck.
