While finishing installing my supertech double springs today (with the head still on), I noticed that neither my intake, nor exhaust valves are magnetic, which would suggest to me that they're stainless.
Does anyone know what the OEM valves are made of in a BP6D? I've no reason to think these valves should be anything other than OEM, but I didn't buy the engine new from Mazda....
