They're all aftermarket gaskets most likely. I'm assuming that from the color of the valve cover gasket and the fact that they're comparing the prices to Pep Boys, etc. Many of those will work just fine no matter what, but some of them I'd feel better about if they were OEM Honda parts. Not knowing the quality or construction of stuff like the head gasket would worry me a bit unless you're just freshening up a stock engine for a daily driver. The most expensive thing in there is a head gasket, and that's the one thing you don't want to worry about.

Basically I would say it is a good deal only if you don't care about the quality of your gaskets.
