Cylinder head water manifold (early)

[Chris KC]

Completely agree with Bob, having recently rebuilt an engine which has run on plain water for many years, I resolved to use a corrosion inhibitor from now on. I rejected glycol antifreeze on grounds mentioned above. I'm thinking of using Redline's 'Water Wetter' as it offers both anti-corrosion pack and better cooling performance than glycol, while sounding generally less toxic than some of the other offerings (important when it blows off in your face now and then).
