I'm curious about the sticker with barcode on the back of one of the heads.
Also, I know we can decode Porsche engine numbers, but is there some formula for decoding GM numbers?

I listed that based on the numbers but here's the breakdown
3MA is the GM build code for a 2004 Pontiac GTO LS1....roughly 345hp
Casting number 12561168 is a LS6 or late LS1 aluminum block (both 5.7L)
The 2004 Holden Monaro / Pontiac GTO, Chevy SSR, and the C5 Corvette were the last vehicles to use the LS1, both replaced by the 6.0L LS2 the following year
The etched serial number won't tell you anything
