One of the pros to the DOHC, is that one can use a more aggressive cam grind and still maintain a good idle.
One of the Cons of the DOHC is that the engine even though it is very well designed is not as simple to work on as a pushrod small block. Assuming you don't have 17 miles of hose and tube on your pushrod V8. What I am referring to for one thing is valve guide seals, with a SBC you can fairly easily change them with the engine in the car.
They say push rod engines make better torque, however I do not understand the physics involved with that assumption. I think it goes back to the cam grind utilized in the DOHC engines and stroke of the engine.
