wonder why the snow stuck to one side longer than in the other side?

You don't have a longitudinally mounted engine, so the only other explanation would be the exhaust manifold...

I wonder, if after sealing the hood, it wouldn't be beneficial to divert some of the heat from one side of the engine compartment to the intake side... it might help to preheat the air going into the engine. I'm not sure what other benefit you would get from it, other than a uniformly heated area under the hood...

Obviously, the header area is going to be hotter than the rest of the engine bay... I'm just wondering if you can make it so that there's less of a difference between areas.
