    I agree. I've been doing a lot of reading and lookig at cams too.
    from what I've read the reverse split cams don't perform as well as standard split

    Lift has virtually nothing to do with PTV clearance since max lift occurs while the piston is near bottom dead center (BDC).

    Duration is the biggest factor. The longer a valve stays open the closer the piston approaches. LSA and timing advance will also affect ptv to a much lesser extent.
