Default What Patriot Cylinder Heads Do I Have? LS6 Engraved In Head

Recently purchased a used engine with Patriot Heads.


Trying to identify what Patriot heads I have? (see Picture Below)


I believe they are the older LS6 style head because I see two stamps on the driver side heads In the front they say Patriot in small letters and in the rear its says LS6.
Passenger side head says 035.
Any help would be great!

I'm no longer with Patriot but can give you some information. These are going to be a set of the older "LS6" Style heads. There's not a way to determine what combustion chamber size because these heads were done before June 2004. Shortly after I came to Patriot in June 2004, we began issuing each set of heads a specific serial number. More than likely they are 59cc.
