And you’ll likely need them anyways with most of the aftermarket cams.
Why mess with aftermarket pistons? I don’t get the appeal. If I was you, I would go with stock bottom end and deck the block if you want more compression, though I don’t think that’s necessary. Chinagap intake, 650-750 carb, mopar electronic ignition and a regrind about 210-220@ .050 you’ll have a decent runner.
