Edmunds head on ebay

dougson

There is early interest in the old aluminum Edmunds head on ebay. Has issues but I guess repairable. Does anyone have old catalog information on these early Edmunds parts? How old is the head? What compression ratio did it provide?

I have seen them advertised in old Speed Age Magazines circa 1952 but do not know the comp Ratio. Its probably one more Point higher than a stock Hudson aluminum head but more nogalistic with the Period cooling fins.

The Edmunds heads look cool but I once asked Jack Clifford about them and he didn't have anything good to say about them. He claimed they were prone to having porosity in the castings which might explain the cracks in this one.
