Stock copper plugs are 0.035." No question. No one should be saying otherwise if you're asking for factory specs.
CAN you mess with the formula? Heck yes, but that would be opening a can of worms called customization/modification. I, for instance, have 0.050" gaps, but there's A LOT more to that story--I have iridium plugs, and they're powered through Magnecore wires by an MSD coil fed by an electrical system that has larger batt/alt cables than stock.
