I wouldn't worry too much about heat soak with the aluminum intakes. We did some testing on them at the shop and the tarck and there is no discernible loss of power over the composite intake. Heat soak only becomes an issue when the car isn't moving or driving slowly. The intake moves the air so fast it doesn't heat up much at higher speeds. Don't get me wrong, there is a slight difference but it is so little just get an intake that you like and flows the numbers that you need. Another common myth we dispanded was the 90 MM intake on anything cam only or less. On the dyno it did make more peak HP on a cam only car by 3 over a 78MM, but the loss in torque and the fact the peak HP was so high I think a 78MM car would stomp it at the track. In the end you have to decide what you want to do. Personally I don't think you need a 90MM until you hit around the 475-500 RWH range or go with a big dispalcement engine.
