Austin 12/4 Cylinder Heads
 |
This high compression head is showing part no 1B255. 03 |
 |
This is the low compression head part no E9019 |
 |
See here, the hole through to the water jacket! it must have been a faulty casting because there is no excessive rust shown anywhere else on the head |
 |
This shot shows both the HC and LC heads. There is a huge difference in the combustion chambers |
| I believe that the high compression head is of Ricardo design. Ricardo was a patented combustion chamber design. |
