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

Two silver (light) springs and the full 28 degrees of centrifugal seems to be the hot ticket! Static timing of 13 degrees BTDC with the vacuum advance connected, and it would probably like more.

What is the actual timing with the advance disconnected? That's your baseline to which you add the centrifugal advance.
