400 rpm between peak and cut is fairly standard, and there's no point in more RPM if they don't deliver - may as well shift once the engine has done it's best in that gear.
I'd go stump puller - it'll likely still rev much harder than the stock motor and it's a street car. Big torque on the road is always more fun, more often.
