  • Engine: Valve seats

    I just did a valve adjustment on my PowerHawk. The previous owner said the motor has bigger valves, cam, 60 over, Cadi valve springs. I adjusted the valves when I bought the car a year an a half ago, all were too tight, most practically 0 lash. So now, 18 months and 10,000 miles later, all were within spec. My question, does this mean I probably have newer hardened seats?
    Thanks,

    I don’t know if those are Caddy (Cadillac) valve springs, but they are certainly made for high revving since those are dual valve springs. Definitely not stock or performance Studebaker there.

      One other thing...

      The heads appear to be a "reddish" color which was certainly not stock for a PowerHawk thus being a 1956 engine would have had sort of an acqua, (bluish/green) color.
