is there a top or bottom to 2.0 barrels (cylinders)??
 

I can't tell from a new set that I got which way UP is!!! I don't want to mount them upside down, but they look perfectly symmetrical. Is there a way to tell, or does it even matter, which way is the side that faces up or down on 2.0l cylinders?? I know the pistons matter, but what about the cylinders??

Thanks.

uh,oh!

That doesn't help!!! :)

Is there a way to tell which way is up or down? They're not installed yet, but I want to make sure I have them set right!! Thanks!

Ok, I think you thought I could not tell which was the head part, or the case part. Come on, that's a no brainer.

I mean which direction to orient them - since they are symmetrical. Or are they..? That's what I wanted to find out!!

Usually one side has longer fins and that side faces down. However I'm not familiar with 2.0 motors so maybe they're the same and it doesn't matter. Hopefully someone familiar with 2.0 cylinders can chime in.

2.0 cylinders are the same shape top and bottom, so it doesn't matter which way they go.

Thanks John, I appreciate the help! They looked that way, but I wanted to make sure!!!
