I just got a lq4 from my boss for free. I don't know what year the engine is and I know that it's kinda important for the head bolt lengths and cam bearing sizes or at least what I've read online. The casting number on the back passenger side is 12551364 and I can't make out what the front casting number is on the front by the head. I attached a picture of it.

ok I'll take one tomorrow while at work. I says 6.0l on the block so I know for sure it's a 6.0 just don't know the year.

You can just measure the head bolts hole depth and the cam bearing diameters (I would recommend measuring the cam bearings before ordering anyways.)

From what I've seen that's pre-2004. The number got much larger with the later ones.

alright thank you. Just by chance do you know the length difference if not no big deal.

Bradyls10

alright thank you ill double check the length of the head bolts when I pull the heads off as well
