I reciently got the bad news my rocker arms need replacing/recoating on my 99' 996s. In addition I'm told the cam shaft should be replaced. The repair cost warrents looking for a replacement engine. Can anyone tell me if a 998 engine will fit into a 99' 996s frame without modification? Also has anyone had any luck getting ducati to flip the bill for the rocker replacement in recient years. Finally how does one know if the replacement engine had the ugraded rocker arms? Thanks for any advice on this.
