    Hey all!
    What's goin into my car...
    Fully ported heads stock valve sizes
    Ported LIM
    Ported M90 gen 3
    N*/LQ4
    VS Cam
    Headers

    Currently it's all sitting on my workbench with LS 90lb Springs & Retainers....

    What I'm wondering is should I upgrade my springs to crow 105s or should I go even bigger with a double roller?

    Thanks!
