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

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

DrCharles, I did check the static timing with the vacuum advance disconnected, and IIRC it was about the same as when it was connected, but I'll double-check to make sure. I think maybe that is because my heads have been heavily ported and the intake manifold match-ported to the heads, so the intake vacuum is low at idle.
