All of this information is older than jbcomp so it may not stand today but mechanical advantages and "guidelines" don't change much, metal and lube quality can but math formulas seldom do. This is not meant to flame anyone or disagree, just food for thought.
How do you know how old I am? (but yes I'm sure it is)

You can EASILY over time and engine and lose power AND most importantly power band. The combustion chamber has alot to do with this as well. I have seen too much timing KILL and engines power and power band 1st hand here on my dyno. SO I suggest more mild timing alterations and ease your way into it.
I've never really been known to "ease" into things, I'm more known to bite off more then I can chew (sometimes) like puting a 4-stroke plane engine in my CRT
