This rare Honda head is hard to find on an even harder to find H23A VTEC blue top engine that came from the; '98-02 japanese Accord SIR Wagon (chassis CH9), '98-02 european Accord Type R (chassis CH1, not the standard red top H22), and possibly a Honda Prelude either produced for: Japan, Europe, or Australia. Any info. on where I could find this would be very much appreciated. Thank you.
