I have the skunk2 pro series valve springs and the titanium retainers for a b series vtec head, and i am wondering if the valvetrain would work with the blox b cams, meaning are the pro series valve springs too stiff for the blox b cams? I am trying to find out what are the specs so i can figure out what valvetrain to run.. I would like it for somebody to show the specs or where i could find the specs so i could figure out if i need a new valvetrain.. thanks
