Photo of Combustion Chamber of Head Casting 2843675?

My 318 (1979 block casting) was rebuilt 10 years ago and runs great. I have no idea what the combustion chambers look like in the cylinder heads she uses. I know the valve size must be 1.78"/1.50" but curious about the combustion chambers.

If anyone has a similar head casting laying around, I would appreciate seeing the posting of a photo of the combustion chamber. Thank you.
