    Yup,those are the ones. Kinda heavy,but plenty strong. I ran them in a whole bunch of 600+ HP nitrous engines over the years. The last set I had,I had fly cut about .070 in the valve notches,and routinely shot a 300 HP plate thru it in an 8000 rpm engine. I would melt spark plugs,and push the best head gaskets out,multiple times,and the pistons held up fine.

    You can also soften the piston if you think you might risk detonation.
    I have no clue if it helps on a street engine, but it definitely helps us.

    probably means to smooth the sharp edges on the dome

    Can't see the ??, that poster is on the block moron list, but yes, we soften all the possible hot spots on the piston and head.
