i have a spacer under mine. if you use a 4 hole spacer you gain a little bottom end if you use the open hole spacer you gain a little top end. i dont think they make a huge difference but maybe 5-7 hp.. i think the 460 breaks the exhaust studs is because of the torque when the motor twists against the exhaust. i maybe wrong but my 460 has 1 or 2 broken also, its very common.

Exhaust studs breaking is common due to heat fatigue. You can use candle wax and a blow torch to remove the broken studs. Just heat the stud until it glows then stick the candle against the glowing stud. The wax will lubricate the threads to the point that the stud will turn out a lot easier then just using heat alone.
