| To RHC.{R. H. Coverley - Production Engineer} X319 Hs{Lord Ernest Hives - Chair}/Swd1.9/JH.3.10.36; Phantom III. Will you please remove the 4 port cylinder heads complete with induction pipes off the test bed engine No.8 and fit into 32-EX chassis (No.13 Unit) now in the shop. The 4 port head was designed for an exhaust heated hot spot but for the present this has been dropped and we have substituted a standard water hot spot. This means that the water feed pipes are for the present a mock and are taken from the outlets and this will have to be similarly arranged in 32-EX. The standard cylinder heads and induction pipes complete when removed from 32-EX to be fitted to the test bed unit. We do not want the carburetters interchanging.
