Before going with a specialized EV spread such as Infernape's, you have to ask yourself whether it is relevant to any Pokémon you could potentially face. I would not recommend just ripping it off of Smogon without knowing why it is used. Read the analysis and find out what exactly it allows you to defeat, and if none of those Pokémon apply to your environment, you should probably either go with a more straightforward spread like 252Atk or do damage calculations yourself and see if a mixed EV spread allows you to defeat threats that you can actually face.
