In 2013 I got an early head for my S/N W312 engine. It was rusted together pretty tight
These springs and retaimers were used up to engine number W84246
I was able to get a set of NOS early valves for this
Looking pretty rough and rusty starting out, the head cleaned up nice
With the valves lapped it is time to assemble
What the tops of the early style valves look like
Everything cleaned up and ready
Ready for action
