Gen III Head Part Number

Gen III V-8 Cylinder Head Shootout
If you want to know what cylinder heads you have on your Gen III V-8 engine, look for the last three numbers in the casting part number. The close-up image shows the exact location of the last three numbers of the eight-digit casting part number located next to the rocker cover seal lip at the far right end of the head on the exhaust-port side of the head. For instance, the "243" cast into this head signifies it is an LS6 head cast made between '01-'04. View Related Article
