CYLINDER HEAD. X4098 X4099 We send you herewith the original of LeC.2233. shewing the improvements it is desired to make to the Eagle(Aero Engine) 16. cylinder head. Would you kindly send a blueprint of this drawing to RG. {Mr Rowledge} for his criticism. It will be remembered that in addition to increasing the valve diameter and the cross sectional area of the induction pipe and gas bends, that we propose to increase the valve lift .050 if possible, and also increase the length of the inlet cam so as to obtain a later closing point of the inlet valve.
