If I just gel my tungsten lights with daylight conversion gels, I should be fine to shoot on daylight stock, correct?
Correct, but the blue filtration will cut the light output. For example, the equivalent of a Wratten 80A (3200K to 5500K conversion filter) has a "filter factor" of 2 stops:
Usually best to match the stock to the light source if you can, but gelling can help match light sources to each other (e.g., filtering daylight coming through a window to match tungsten lighting, or vice-versa).

If you need the extra exposure, you could shoot ungelled and then fix it when timing.

I would just use a filter. It would be alot quicker and will save you alot of time that you may need when you are shooting. But if you don't have the filter then I would defintley say that gelling the lights would be the next best thing.
A camera filter won't help if he's using the tungsten lights in a daylight-lit interior.
Either way, an 80A camera filter or Full CTB gel on a light loses you two stops of light.
