    I know Pro Comp initially used poor quality valves and springs in their pre-assembled heads. Has their quality improved? Would I be better off buying bare heads and building them from scratch? Engine is a 496 with a .575 lift flat tappet cam.

    Asked by: runningwithscissors
    We have not had any issues with the quality of the heads - It looks like the lift you are using is a bit over the recommended maximum for the springs that come on this head.

    CAN YOU GET THESE HEADS WITH A HIGHER LIFT SPRINGS AND CAN YOU USE THE STOCK PUSH RODS AND PUSH ROD GUIDES.

    Asked by: greenman
    No, you would need to purchase the "bare" heads and add the components that you want for your application.

    For these heads to work with roller cam you must change the valve springs.
