Never heard camelback before until I read this ancient post
Do you mean camel hump which is also called double bump or double hump? Look at the end of the head right at the lower edge. A rectangular casting boss with 2 gumdrop shaped casting bosses on top of the rectangle.
Then they could be 194 or 202.
They sold for $100 pr used in the later 60s to mid 70s. The price is still the same.....Glad I did not stock up
Some 327 were used in Vetts. They were rated at 365HP and the fuel injected 375HP. They use the 2.02 heads. They had the double humps.
I'm not to sure if the 327/ 350HP were using the same 2.02 heads. I may be wrong. I know they used a milder hydro cam on the 350HP.
