Hmmmmm.... Would I re-use that piston?
In a 200 HP, 4000 RPM truck engine: yeah, probably. A little work with the file to knock down all those rough edges (those are future pre-ignition/detonation risks) and I could live with one cylinder that is 1/4 point off in the compression ratio.
But in a 6000+ RPM hot rod engine? Hmmmmm...
Considering that it looks like a generic Sealed Power piston, it's only gonna add about $30 more to the repair bill if they're cast pistons, and maybe $60-$75 more if they're forged... Cheap insurance. JMHO
(Side-bet: I'll wager that those are cast pistons, and that what you got there is a generic parts-store rebuild long block- I can't imagine a performance engine builder using inverted dome pistons on a street/strip performance engine build- again, JMHO)
