I have tried to search...but have only found out so much info....

I know the LS1/ LS6 has casting #'s on the head and on the block...

does anyone have info about the sticker on the driver side rear cylinder head?

or about how to decode the stamping (etching) on the driver side of the block?

on the pad on the driverside of the block I have "K126 726"

from what I have read, it should be 9 characters....

any info out there?
