Unless you're seriously going all motor, then no, run the stock 8* timing split. If you miss the trailing timing to the point where it fires before the leading, you have a chance of pre-ignition and damaging the engine, (i.e., damaging an apex seal). The part of your question that worries me is your asking how to set up 0* timing split. If you were serious about racing in this class, then you would know how to set it up.

If you want more info on timing split, read the threads that popup at the bottom of the page.

they ran 0 split for reliability, and since they moved the spark plugs on the racing housings, power is ok

for a stock 12a a little split is better for power, and cross fire isnt a big deal on a lower revving street car

it's the degree of eshaft rotation from when the leading fires til the trailing fires.
