i am a old hot rod guy and when you wipe a lode on flat tap cam small block 350.you must do a complete tear down of the motor,check to see if there is no other damage,clean out and remove all metal shavings.if you do not remove all lose metal from the wiped lode.down the road you might have other problems caused by all the metal still in the motor.so make sure they do it right the first time.otherwise you will be going back to the dealer for more repairs.good luck
