    1948 tappet blocks, Iron or Aluminum?

    Robbie or anyone else who may know;
    How late were the iron tappet blocks used into 1948?
    My VIN is within a few of 1500 and I have both iron and Aluminum blocks with the correct 48 casting marks.
    Just wondering which I should use.
    Thanks
