NOS 2380P pistons?

[Jonnylightening]

I bought a NOS set of 2380P pistons. I didn't get any papers on them. Can anyone tell me what size rings? I'm guessing 5/64, 5/64, 3/16 but would like to make 100% sure before I order

That would be stock sizing., yes.
Those will be about 8.2 with a 70 cc head
Better run a 63 chamber for some umph

I'm using them on my magnum with my EQ heads.
