Outlander 800 valve covers

Hey guys,
Like I said last time, just picked up a 2009 outlander 800 gorilla edition. Well I can see that the valve covers are leaking a little. Well I did some research and warped valve covers are apparently a common problem with older valve covers. The new ones don’t do it according to them. So I was just going to replace them with new along with the gasket. However, I can not find them for sale anywhere!! You guys know where I can get them? Are there better options than stock?

Thanks!
