Help identifying pistons.

#1
I bought the car several years back and drove it a while and parked it with the hopes of upgrading with ported heads and having the block bored over.

I finally got back to working on my car and decided to install ported iron heads I purchased here. I purchased all the gaskets and head bolts and when I removed the head I was surprised with this. I tried to look them up with no success.

Do I have .30 over bore pistons. If so it is a nice surprise.
