Sealed Power 2350p 440 piston specs?

Sealed Power 2350p 440 pistons. Anyone know the CH on these? I've heard both 2.035" and 2.067" but...it can't be both. Opinions?

2.035 which is around .050 in the hole depending on what the final deck height is. They will give you around 10.3-1 with steel shim head gaskets and closed chamber heads....again, depending on what the final deck height and cc of the heads.

I just checked mine and they are .020 on the hole in a 440-3 motorhome block, never decked

Keep in mind that the late model blocks may have a very large bore chamfer and that adds a significant amount of volume to the chamber. My 77 block with KB 237's, 915 heads and steel shim gaskets is only 10.1:1 CR.
