I ordered a 65mm tb from 60degreev6 and im getting a new uim to go with it but the thing is they have a stage 1-3 3400 uim and stage 1-2 3500 uims. Am i safe to say that either of the 3500 intakes are better then all of the 3400's? I e-mailed the store but havent received a response. I also plan on the phenolic spacers to and is there any certain conflict with port size in relation to the spacers or such. Thanks.
