You have some crazy posts, guy...
I would suggest reading up in some hot rod magazines or just forums in general on engines. Get some good exposure, as it can get pretty hairy around here if you're too green!
With that said, oversized valves simply give a larger cross-sectional area for air to move in/out of the cylinder. Depending on the engine, modifications to the pistons/deck height/etc need to be taken to make sure there's no interference since the valves at tilted wrt the cylinder bore. Timing really has nothing to do with this on a basic level, though if you're moving lots more air you need to retard accordingly because of the extra density (fuel molecules will be closes, flame speeds are faster). Most factory ECM's run ignition up to knock then retard slightly, so they can take up the little slack if the valves is all that's different. That is, assuming you meant ignition timing. Cam timing is something different altogether.

you do this by searching, reading, learning. it was almost one full year after learning that I made my first post on this site.

Exactly, I lurked for 2+ years before I started making serious posts, because of that I haven't had to ask a quarter of the questions that most new people ask, if that.

datdude_enzo: You could spend hours trolling the forums after someone tells you to search, or you could spend the time reading that book. I would go with the book and if you still have questions after reading it, start trolling.
