Lots of option on that site - do you have a recommendation on one - or they all should work?

I would say get the same brand and model you have it will make it easy to put in...

There is a 2nd hole on the intake manifold aside from the main one and bolt holes for the carburetor. What is it for? I finally found the right gasket but the YFA carburetor it has always had on it, does not seem to match because of that hole. It's the hole that is big enough for your finger. Am I missing a part, like a spacer or something?
