That is a fairly primitive distributor so you'll just have to do the best you can. First step is to set the total advance where you want it which is probably somewhere in the low to mid 30's. I've never run the Brodix heads so I can't tell you how much advance they want but I'd start at 32 and work from there.

Advance at idle will depend on the bushing size you install. A performance cam will typically want a fair amount of advance at idle but with the black bushing you'll be limited to what you can give it. The advance curve will depend on a bunch of other factors but typically for a performance application you'll want the advance to come in fairly quickly. As pointed out above, all of this info is in the instructions.
