Default LS6 Head Identification + Help

Can someone please offer help on how to identify the LS6 style heads on a built up LS1 engine? Is the p/n 12564243 correct and where are the ID p/n 's located? If the numbers are internal, are there other ways to identify the heads?
The engine is for sale now and something I am considering since it has many of the mods I am already contemplating including LS6 style Intake and an upgraded cam. It has never been on the street according to the owner. Are there other things I should be asking the owner about when buying an engine like this? I tried to get the engine builders phone number so I could talk with them but so far no number after several days of asking, just the name. I tried to look up the name on a search with no luck. That has made me nervous.
Thanks !

the last 3 digits on the head are 243. so those are probabally them. they are located right below the bottom right hand corner of the pass. side valve cover.

Default Head ID help

Thanks Silverbeast. I assume then that p/n 12564243 is correct and will look for that number on the pass side head by valve cover.
