The book calls for the front end to be repacked every 80,000. I don't know why, but that's what it says.
The timevalve exhaust is good stuff, but making it fit can be tricky. You do have to take down the tank. You will need a torch to tweak the parts to fit well. Also go to Autozone and get some header wrap to cool it off on top of the tank!!
