Is there an easy way to tell if a 72 402 ci has oval or rectangle port heads? I want to get a carb and intake for Dad's truck to put on it this weekend, but I don't have time to get the stock intake off until then.

Did they only use one or the other, or both? Any obvious signs to look for, or casting numbers?

Thanks!
