edit: It's not the 2399. That's Mk4 with a dome. Gen 6 are flat top if you're using Gen 6 heads. I'll see if I can find part numbers.
There's a 1602 at the top of the rod. You can't see it with the piston still on the rod.
The pistons in my 69 that I built the same motor for a few years back has Sealed Power H749CP. Same pistons, but I have .030" over in that.
According to Mercruiser, the numbers for the rod are:
NLA 614-3553 superceded by 8M0030663
These aren't anything special, but I want to make sure they're the same as the other seven. I'd rather not have to buy all eight if I only need one.
