TOTAL Timing Advancement for 402 BB?

[jugadro]

I'm trying to find out if anyone knows the degree that total timing should be set at for a 402 BB. The place where I had my distributor rebuilt at suggested I set my initial timing to 14 degrees (with light springs on my vacuum advance HEI distributor), but it still doesn't feel quite right.

I was told to pick up an incremented strip specific to my harmonic balancer, wrap it around the balancer, and it will show me where to place a mark for the total timing, but I can't find them anywhere. Any tips?

Thanks much.
