LR4 Head Casting Numbers Hey all, I'm new to the forum so apologies if this is the wrong thread for my questions.
I have an LR4, or so I think, that I am using for a Jeep LJ project. I found some dimple numbers on the heads that I can't seem to identify. Can anyone help?
Block casting number 12567392 - 2005 era LR4 block, correct?
passengar side - 711019137848925 (rear of the head)
passengar side - 7110T3744776 (front of the head)
driver side - 71101910915992 (front of head)
driver side - 7110T3754776 (rear of head)
Thanks,
Lane

Once you have the 3 digit casting number, the other numbers are basically meaningless. They might indicate origin, location, date, etc, but the 3 digit number is what you need to pay attention to.

I guess I'm confused on the curiosity. An 862 head is going to be 99.99% identical to another 862 head even if all of the dimple-punched numbers are completely different, making them almost irrelevant.
Pay attention to what casting the head came out of, not what someone stamped into the side of it afterwards.
Btw, they stamped numbers are usually a combination of the GM part number and the serial number that contained date codes for the heads.
