4.080 -4cc Wiseco/TSP pistons
yes, i am awhere that a FT piston with valve reflief will have a negative volume, but ive never seen a Flattop with a small dish/reverse dome... opinions? anyone else using this piston and have pics.

You can always call and ask what the -cc is to determine your CR. It's common for dished pistons to have the valve relief as well however, those are very mild dished by the looks of them. Check the parts online or give them a call.
