John: I have the 1955-58 Chrysler parts book that shows 1556156 as the head for 1955 New Yorker, Imperial and Crown Imperial. The book does not show a separate head for the 300 and does not list the 1556157 number. I have recently asked the server group if there is a difference in 1955 300 heads and others, with no response. A different part number is shown for 1956 and 1957 300 heads. Perhaps the 1556157 is a special 1955 300 head. More likely truck, industrial or marine. Where is that part number located on the head?
