Jim,
Very difficult to recommend an initial timing with so little info about your
engine.
It depends on a lot of things like which L20B (200B, Bluey S1 or S2)
compression ratio, carbies, dizzy, even fuel used and is it all stock or
modified. A stock 200B L20B runs initial timing ~16 degrees with all of the
pollution crap connected. With all of this crap off the engine and just a
normal vac line attached to the carbie around 12 degrees is normal so
somewhere in that range is about right for most L20B's. However, fine tuning
by playing with it is the best way to find out what suites your engine. Also
by fitting a hot cam doesn't necessarily allow you to increase the initial
timing, it depends on so many factors, and make sure you don't let it
detonate. Audible detonation means it's around 2 degrees to far advanced or
the dizzy curve needs attention if it only detonates in a particular rev
range when at wot.
regards
Terry
