Hey guys, I'm looking to buy a timing belt kit (Timing slipped on the passenger side head, making it hold only 120PSI of pressure on those cylinders vs 180PSI on the drivers side). What's a good kit to buy? Which one is high quality and which ones should I stay away from? I called NAPA, and my guy offered me their $580 kit for $409 dollars. I'm new to B6's so I don't know what to get.
