Tuning For Detonation

I agree. I've read over and over slants don't like a ton of total timing. I really wanted to try about 20 initial and 30-32 total, but the plate is not offering that, even though it's marked to give those results. I have an email in to Don so we'll see what he says.

They don't. 32 degrees full advance is where mine pulled best .
I think you should put the stock plate back in it and remove only the heavy spring leaving the light one that should give you about 18 at idle and 15 advanced left in the curve. Or screw a bolt into it and grind both sides off to eat up the advance.
