Cylinder Head Identification?

[69 Muscle]

Does anyone know how to identify heads off a 69 camaro 350 block?
I am trying to identify whether they are 58 cc, 64cc, 68 cc, etc...Can anyone help? The number on them reads: 333882 GM 1T
Thanks Paul

882 heads. Those aren't original 69 heads. They're more like 74-80 heads; smog-ready, with what appears to be 76cc chambers and 1.94/1.50 valves.

Google search says the 882s are prone to cracking. One site said that stock they flowed 137.2 CFM on the intake and 95.4 CFM on the exhaust.

Hope this helps.

Thanks for the help Derekf.... I have been trying to identify the chamber size for a couple weeks...
