spark advance question

The graphs on tunerpro rt show my spark advance to be around 13.something. i'm unsure exactly what spark advance is besides the fact that it has something to do with timing but i'm wondering if this is where it should be or not. I've been trying lately to pick a part things one by one to figure out why i'm only running 14.3 quarter miles with the mods I have. I went and bought a distributor wrench extension the other day but from what i've found online i'm still unsure on how to check that the timing is at "0". if someone could dumb this down for me it would be greatly appreciated.

The timing marks line up for both TDC #1, and TDC #4 cyls. Lining the marks up is not enough. You must ascertain Which cyl's TDC (#1 or #4) the cam (valve action) is on. You can determine this by one of two methods:

A: With driver side valve cover removed, rotate crank until #1 Intake valve closes, then about 90º of rotation later the marks line up. This is TDC #1.

B: Remove #1 spark plug. Place your finger over the hole. With a remote starter button (or a helper on the key) blip the starter in little bursts while watching the balancer. When you get the "PFFFT" of compression, look , and you should see the mark getting close. Usually within 45º. Crank up to TDC by hand.

These are the two methods I use. I'm not aware of any other methods that are as sure-fire as these.
