The cam timing depends on the cam you are going back with. Most aftermarket cams come with a timing card and it tells you where they expect you to install the cam, which is usually at TDC.

On the rocker ratio, I wouldn't go beyond the stock ratio of 1.73 with your lift. Tim said those rockers should work, meaning there's a chance they won't. But higher lift rockers would increase the odds of bind significantly.

Rotella and other diesel oils have a lot more ZDDP than oils for gas engines. I would at least break your engine in with one of those oils, and maybe run it even after break-in.
