My money is on the longer intake port, thou if ur planning to boost the engine the short port will work better since it wont reach sonic speed as quickly.
I mean to say on an NA the long port to the valves will help accelerate the intake charge helping both mid range and top end. the shorter wider port will flow at lower speeds, thou it might acctually work better at real high RPMs. this lower speed is a plus in boosted engines, but we r considering that you will be reaching either head's flow limits.
