C8AE 6090-J Cylinder head casting
By Royce Peterson - 02/12/2002 4:58:27 PM; IP 63.87.74.238
This casting was used to produce three different heads. The Cobra Jet (before January 1968) head can be identified by 16 holes on the exhaust port and the higher port location.

The Cougar GTE 427 LR head can be identified by its lower port location and 14 hole exhaust pattern.

The 427 LR service replacement head can be identified by its high port location and eight hole bolt pattern on the exhaust.

All these heads have thermactor holes which are plugged in the case of 427 LR service replacement heads.

All of these applications were replaced by the C80E 6090-N head after January 1, 1968 and all three variations of the C80E 6090-N head exist.
