Still trying to map out a timing curve

The start retard is a cool feature as long as it fires right off at the flick of the key, if it doesn't I would take some retard out of that feature until it does with the engine HOT.

That engine should idle around 1000 RPM or so. Your engine is going to like more Initial timing than 19* , I would say in the 23-24* Range at Idle. It will be way more crisp off idle than starting at 19, It will be lazy where you have it at. Your all in timing should be in the 2200-2500 RPM Range. That is how I would set it up if it were me. I have my stroker rev limiter at 7200 RPM. Yours is pretty low in my opinion. Right when you are in the power it is going to bang off the limiter.

Just noticed you got 4:10 gears too. You are going to definitely hit that limiter real fast.
