Cam Timing

[jujulo700R]

I've got a Raptor 700 that I took the engine apart to put some new motor mods in. I need to put the engine back together but I wanted to know what is the best way to get a cam chain back on and  how do I make sure that the timing is right on it? Thanks for the help everyone in advance.

There should be a dot on the cam's.. Make them level with the head.
