Y-BLOCK CYLINDER HEAD CHART
Note: 6090 is Ford's number for cylinderheads. All heads will have this number somewhere. It is meaningless! 0609 is 6090 upside down.

*Compression ratios listed are from Ford literature and are theoretic figures that exclude deck volume and head gasket displacement. Most published compression ratios are approximately 9% higher than actual.
When engines are rebuilt with composition head gaskets deduct about 12% for actual compression.
Do to the thinness of the deck surface of some Y-Block heads, particularly the ECZ-G heads, it is recommended that unposted heads not be milled more than .025". Posted heads have been milled up to .045" without trouble.
Heads with large "S" in between center exhaust valves are service replacement heads as date codes are after production run.
5752-113 was sold as replacement head for ECZ-G
B9TE was replacement for 5750-471 B9AE was replacement for 5752-113
5752-113 service replacement head from 1961. Not used in production after 1959.
