As long as they work when you test them, i'd have no problem running them on the street. In a race car it's a little more critical to be monitoring the gauges and to be doing so on a constant basis. If one fails you'll see it pretty quickly, but the bigger concern is something in the engine failing while running down the track. If that happens and it's an oil pressure issue, working gauges won't save you anyways. Nobody watches the oil pressure while running down the track if you know what I mean.

You should be fine with those in my opinion
