    cam stamp?

    What is the significance of the letter etched onto the stock cams? I opened up a spare head today which had a "K" on the cam and I am wondering what it means.

    The "K" cam was used in the 8.8:1 Kat equipped i engines.

      In other words, the stock "i" motor.

        Not exactly. There are 9.4:1 and 9.7:1 i engines as well running around in the gray market cars. They have a different letter stamp according to RealOEM.
