| HS.{Lord Ernest Hives - Chair} FROM E.{Mr Elliott - Chief Engineer} ORIGINAL. E2/M20.7.31. (12) 20/7/71 P. 2. CYLINDER HEAD. Y 7050. Thank you for your memo. HS{Lord Ernest Hives - Chair}3/MJ18731. I have hunted out the report I had in mind - e.g. HS{Lord Ernest Hives - Chair}5/MJ17.7.29. - and I see now the proposal to use a head without lips applied only to lower compression.
