Pre-66 heads are a match.
By Dave Shoe - 04/12/2004 8:23:49 AM; IP 216.243.176.34
Just to clarify: The change for FE heads came into play at the start of the 1966 model year. The C6AE-R casting, available in much of 1966 and a little of 1967 was an exception, but all FE heads with casting numbers C6AE-J, C6AE-L, C6AE-U, C6AE-Y, C7AE-A, C8AE, C8AE-H, and D2TE-AA have the repositioned exhaust port, regardless of which drill pattern was machined in. Hooker car headers do not match these castins, but apparently Hooker truck headers do.

The repositioning of the exhaust port was apparently executed to simplify exhaust manifold design for shock-towered Fairlanes. It appears to have been an excessively conservative idea which did not help with performance.
