Keep in mind that an A14/A15 engine's cylinder head limits its max power to about 5500 rpm (without porting). The A12 GX head was good (without porting) was 6600 RPM. So a higher duration cam will loose low end power below a certain RPM, and not raise the top RPM. But it should increase the HP at higher RPMs.
This page explains "duration": Popular Hot Rodding
* The Datsun 1200 FIA cam was .350 lift, and that was good for max 6600 RPM. It was 256 degrees (unknown how measured).
* Stock A12 Cam: 248
