machined chambers

Ford tried machined chambers on the First FE engines in 1958. The problems with those was the sharp edges at the angled spark plugs would cause pinging unless and octane booster was added to the fuel. With some die grinder work they were better than later cast chamber heads. just too expensive for production costs parameters.
