    Hit a snag in the build Gents

    [IMG][/IMG]
    Anyone ever have to run a piston like this? Both number 4 and 7 have a scar. Looks like motor was a victim of valve float by a previous owner. There is no cracking on the underside and it isnt all that deep. Opinions?

    Doesn't cause me a care as long as what caused it isn't happening any more.

    I agree, sharp edges can get hot and cause preignition.

    Already taken off. And the shine on picture makes it look alot deeper than it really is. It isnt even a 16th deep at the worst point. And If no one posts up a great reason not to run em Im throwing em back in. Keep the opinions coming

    Could you lightly heat it to see if any cracks do open up? I don't know, I am asking. I know you don't want to deform the dang thing.
