From what i can tell no one has answered this yet. Its not a matter of why. Its a matter of yes or no and how.
First off. Lets play the what if game.
What if the engine blows up?
Dohc- you'll need an engine used in only 3 cars and pay 1000 if you're lucky.
Sohc- what didnt use it? Its 500 for a fair mileage
What if i want to use a different octane?
Dohc- you cant go down and 93 is the highest fuel octane.
sohc- tune. Done
Not saying the dohc isnt great but i dont think i ever asked opinions about which is the better engine.
