A warped Rochester won't leak gas all over the place. The warped area is above the top of the bowl.
The warped Rochester will leak internally resulting in dead spots or over-rich condition by fuel going into places it is not supposed to go.
A leaky Rochester is usually caused by the float setting being set too high, or from a problem with the float hitting the side of the bowl, or by a tiny turd between the needle and the seat allowing unending flow of fuel. Gas coming out around the throttle shaft is usually what you will see.
