200ci Duraspark & HEI - What initial Advance

My manual only lists a 144ci 6BTC or a 170ci as 8BTC.

What should I run on this engine? It's a 67 block with a 69 head I believe.

I realise some will depend on the individual engine, I do not know if it has a decked block or skimmed head. Just looking for a starting point.
At a guess 8BTC?

Also where do I pull vacuum from? Manifold I presume as the carb port will give me Venturi vacuum at high load/speed so too much advance...

Cheers,

Dan
