Does your car have to pass a strict emissions test. If so, it will have a better chance with 115 In / 115 Ex cam timing.

If the local emissions standard is a little more lax, or if your car, being rather old, doesn't have to be tested, then the engine will run better if the standard cams are timed to 110 IN / 110 Ex. It also helps to dial-in a little more static ignition advance at around 12* BTDC, and a richer mixture will also help performance.
