Those arent as-forged pistons
Although they are high compression pieces, pistons like that are built to be shaped to the chamber. I can only imagine if someone tried to run those, every corner you see would get hot and cause preignition, **** small enough chambers it'd run on diesel LOL
I would assume they are made for tunnel wedge or highrisers, get a good shop to look at them and give you a ballpark on where they can get the compression to.
