    any one here use them? i got a set of 060 o/s 30* valves and seats but the margin is at the outer edge of the valve. i could see how that mite help flow, but im concerned that it mite have a poor seal and be prone to burning. am i being too cautious or is that the proper way to run them?

    Meaning the edge is sharp like a cut-off wheel?
    Or that the seat surface ends at the valve OD?
