Yes the Bolt does fix the issue of the cam gear walking off the cam. Even at 8000 rpm plus. My 2cents on the oil I run 20-50 always have Race or street.(HP motors) 10w-40 stock street motors. I brake my motors in with 10w-30 That is about the only use i have for the weight oil. And Syn. oils are NOT good to brake a motor in on. But once they have some fair miles(brake miles) on them Then It's ok to run it.
God doesn't like ugly.
