Hello,
419753 is cast into just about every B20 cylinder head and does not reflect the exact cylinder head.
Sometimes Volvo stamped a part number into 1 of the flat areas near the center head bolt hole that isn't under the valve cover.
If you can post a couple of pictures of the top of the head and the side with the intake/exhaust ports, I should be able to identify the exact application.
