Will Delco-Remy centrifugal advance springs work in a MP distributor?

I have the exact same MP Performance distributor and the factory mechanical advance setting was way too long at something like around 30 degrees. With the factory mechanical advance setting, factory advance springs and my initial set at 5 degrees BTDC, my engine pinged at the slightest throttle opening.

I reduced the mechanical advance to 19 degrees and set the initial timing at 16 for a total of 35 degrees mechanical, plus around 15 degrees from my vacuum advance for a total of 50-51 degrees advance at cruise.

That’s where I found my ‘69 340 ran pretty strong with no pinging.

I read an article by Rick Ehrenburg questioning Mallory’s reasoning on such a long mechanical advance.
