What head CC might these be

I have an engine I took out of a 98 Z71. 350 FI. The heads have a three tooth saw tooth on the front and back. Looking under the valve cover all I can find is L207 and GM 0. There is a guy that is interested but wanted to know what CC they are. Does anyone know or is there more info I need to provide?

A number would be good - usually in the middle of the head, between the center valves..

Just found out the guy is building a .560 lift roller motor.
