Speed Pro H405 (4 valve relief, low compression) pistons & pressed pin con rods

Mmmmm.... can't use buttons on those since they are flat sided pistons around the pin boss, not round sided.

As said, grooves for pin locks would have to be machined into these pistons for full floating. And as also said... 360 rods are set up for pressed pins... so what's up with the rods? Or is something not being communicated with the machinist?
