Stock gap is 1.1mm/.044in. , but for best performance .047in. is good .... Larger gap = more spark , but rememeber if you go to big you will wear out ignition parts sooner , .047in is a good middle ground ...
In case you're MSD/n2o/Turbo/etc.

msd also has a suggestion list for different types of setups;
Compression Spark plug gap
up to 10.5:1 .050" - .060"
10.5:1 - 13.0:1 .040" - .050"
Above 13.0:1 .035" - .045"
Linear Mode
