I love my polymounts, but that's just me.... I like it rough.

I have stock rockers.... the cam has plenty of lift without having to higher ratio rockers., though I may get 1.6 rollers one day to avoid the rocker deflection.

As for 3.5 over 3.4, if you have the supporting mods in place, and you plan on modding more in the future, go with the modular pulley setup, and start with a 3.5" pulley, you'll be wanting more boost soon after anyways, and it's only 5mins to do a pulley swap after you have the hub installed. You can have any pulley you want, so long as you have the mods to support it.

 

also, replacing that ubend at my shops by me only cost about 30 bucks. Id get it done if I were you!
