Where to Find A G6K Head With Cams?

['95EclipseGSX]

I was wondering if anybody has any suggestions on where to get a good G6K head with cams already on it.. It seems like it would be a lot easier to install if that part was already done, even if it costs a few hundred more. I found a few G6K rebuilt heads on eBay but neither had cams.

why not install your cams into the head? what is so hard about that?
