    will i need better valve springs

    I have an S52 engine and looking to install a set of CatCams 275/275 duration with 11.1 lift for both intake and exhaust. Will the factory springs and hydro lifters be able to handle these cams?

    Yes for lifters and I'd personally run a stiffer spring.

    so the factory lifters will be fine but should run a duel valve spring setup.
