Here are casting code locations.

Post your codes for the following:

- block casting code
- head casting code
- block casting date
- head casting date
- Engine Serial Number

You might likely have a high pressure 1954 block with a 1953 head. 1953 was the transition year between low-pressure and high-pressure 235 engines. The same 1953 235 head could be used on high/low-pressure 1953 235 engines and on high pressure 1954 (and later) 235 engines.
