"Quicker" advance curve; any benefit?

Heck yeah thanks! Glad to see I'm finally getting the hang of it after a decade or so lol... I have a wideband O2 sensor and AFR gauge which helped with tuning but I made sure I didn't get caught up in absolute numbers, I just went 'back and forth' until I found what the engine liked fueling wise. I was running it for a while on 20 initial, 40 total which even then seemed like a lot but I figured screw it, I haven't got it to ping yet let's see how far it can go... turned out it liked even more!

My timing light is a parts store one about 6-8 years old, I'm looking at vintage ones for sale online, mine seems to work fine but it feels like a cheap piece of plastic.

Looks like I need to get going putting in those 3.55 gears
