i really dont see how opting for the sohc over the dohc as the starting platform for power makes any sense.

if your over-all goal is to make the most power "mod for mod", and the b can be built to make more than the d can be built for, it really isnt a damn question.

its like; "i wanna make money off investing! but i want to start with 30 cents in the account instead of 100 dolars."
