Harm by Too Much Advance?
My '81 is not stock, but it's no radical hot rod, either. The 350 is a 1972 4-bolt with 882 heads and non-computer carb and distributor.
I just re-valved it. It has always run Much Better with the timing way more advanced than specs. Can I just advance the timing as much as I like for performance without worrying about burning my new valves or other damage?

Your total timing needs to be 34-36 degrees for peak performance. Advancing it too far will result in detonation and really nice holes melted through the tops of your pistons.
