| X8050 Hs.{Lord Ernest Hives - Chair} C. Mr. Shelton. BY8/H.{Arthur M. Hanbury - Head Complaints} 2.12.24. E.A.C.II. CYLINDER HEAD. It has just been brought to my attention that we are using Cast Iron Guides for the valve stems in the cylinder head. It appears to me that it would be better to have these chill cast Phosphor Bronze since we have altered on the 40/50 from cast iron to bronxe already. BY.{R.W. Bailey - Chief Engineer} Ry | ||
