Unless we know we're talking about a lot more spring than stock, I'd risk it. But if it IS a lot more, then don't just chew the cam up because swapping springs is hard, we need to do something. But I don't see any indication of heavy springs?
I called the shop this morning and they said it's a single spring, and I wouldn't need break in springs. Good catch on that, if the springs were heavier I would've just gone with it and chewed the cam up.
