  • Can I run the Lunati Voodoo Hydraulic Flat Tappet Camshaft and Lifter Kit Chevy Small Block 262-400 Lift: .504" /.525" with heads? Part Number: 638-10120704LK. My concern is springs.

    Asked by: C10_Guy
    These heads are designed to be used with a hydraulic roller camshaft not a flat tappet cam, we would recommend changing the springs or upgrading to a roller cam.

    What do I need to do to be able to run Lunati 73943 valve springs on the the AFR head 033-1034? or are they compatible withe the supplied retainers?

    Asked by: ttoth1331
    Those springs are compatible and should work with the retainers that come with these cylinder heads.
