I've never heard of them, so you might be on your own here. Most people just put in stainless steel exhaust valves and call it done. > Do I need to replace the intakes as well? I'm getting paranoid now about >dropping one but has anyone ever had an intake break? I've never broke an intake, but I have broke 2 exhaust valves on 2 beetle engines. These both broke while at highway speed running cheap gas though. I didn't have any idea how many miles were on either engine. When the valve head broke off the first engine it made a big mess inside, breaking the cam and the rod in several places, along with shattering the piston, but it never leaked a drop of oil. The second one was less violent, only shattering the piston, bending the rod, and breaking a lifter bore off. The first engine got rebuilt and had over 27,000 miles on it when I sold it in a car last fall, and the second one is now only used as a mock up case. I hope this helps.
