distributor springs light enough ??

I'd get rid of the big loop spring. Put a lighter spring on it.

Total is only done when it's actually all in, not some predetermined number like the mopar book likes to spout. If you are seeing timing still coming in above 2500, you need to keep going until it stops advancing. If that's 4K, so be it. Those big springs will hold off timing for a long time, they were there to reduce emissions.

20 + 16 is 36... not 34... :)
