Questions about this 360LA combo?

I believe those pistons in pic are the standard 360 LA smog pistons. They are just like the ones I removed from my 1975 360 LA block. They are called "Dished" pistons. Mine were roughly .100 in down from the deck. I'm installing some Keith Black valve notched domed pistons in mine, when I get the block back from sleeving #3, and boreing.
