I just cannot tell by the picture if a composit cone or not. If it is composit then my other suggestion is the way to go. Danny should be able to tell you where he is getting the 00 grease from. As far as any mods to the engine If it is modded Tony would have etched the information on it with a dremel. Give Tony a call he will give you all the details just be prepared to spend some time with him on the phone.
