    Hey, one of those heads says 400 and the other 425. I think the 450 head is different. Super cool regardless.

    I agree. Those look like GS 400-425 heads, which are the same part and based on the GS750.

    Yes, they are 400/425, my bad. We do so many of these, along with the 69mm big bore cylinders..
