| X219 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Mths{Reg Matthews};29/KW.25.10.34. High Compression Bentley Cylinder Heads. Will you please replace the 1.500 dia. inlet valves in the 7.75:1 comp. ratio cast iron heads, these valves are at present in the alum. head on B-4 unit. We should like the original 1.450 dia. valves refitting to the alum. head, and this will require new inserts making. We should like the cast-iron head completing as soon as possible.
