Cams?

Hey guys, was looking on the internet for performance cams for my vtr and didn't really find any. My bike is nearing 50k and I'm gonna pull down and refresh, plus the cam chains are making noise. I've got manual tensioners, looking for some cams and pistons to up performance, anybody have any suggestions?

How much performance gain can be expected from cams alone? Or maybe cams plus a +2ish overbore?

That really needs to be asked of a Roger Ditchfield type.
But my guess is not much over all, but more of a how and where that available power is found
