    So here are pic's of the K&N HP-3002 oil filter with the break in oil. Maybe an hours run time on it. In the bottom there was a small amount of metal I could feel like fine sane paper between my thumb and index finger. All the flaps pretty much looked the same. Maybe I need to look on the inside of them too? Oil was clean in clear pan I drained into. This is the first time I've ever cut into one before.

    That's normal for a new engine especially during the initial break in . My engine had the same amount of metal in the filter screen

    This is what I use for inspection ... these Moroso oil filter inspection screens part #23845

    https://www.moroso.com/engine-saver-pre-filter-screen23845/

    These screens allow for quick visual inspection and fit between the filter and oil filter pad

    I gotta say,I havent had any of that on both my 454 break ins,at all.I cut all filters open,all the time.My 468 is a flat tappet,and my 454 is a roller.Im hoping that was some construction debris left over you guys are seeing,that freed up and exited.

    In general, YMMV
    Like most things; with filters, there's a trade-off.
    Race oil filters flow lots more oil volume than standard filters because race filters' media is more coarse than standard filters' media.
    Consequently, most standard filters' media can more readily capture smaller bits than most race filters' media.
    Each type filter has its place.
    And yes, it's good to add a moroso pre-filter screen; no matter race or street.
    JMO, in general, YMMV

    Out of curiosity, how do you cut the filter to ensure that the filings don't wind up in the filter media, causing false alarm?

    Use a cutter designed for cutting filters.

    Lol, learn something everyday. I've got one of those in a tool box in the garage. Hung on to it out of some tool boxes I cleared out my dad's workshop. I thought it was essentially a pipe wrench. Humbled once again!
