Where Can One Find Published Factory 360 Piston Compression Height?

Now I gotta ask Rapid Robert what the dish pattern was on top of his 360 pistons. I ask because the Silvolite catalog lists his CH of 1.605" as being for Magnum vintage engines ('93-'01). Those have a sorta-rectangular shallow dish, like 2 D's back-to-back. For the earlier LA, Silvolite lists the CH as 1.576 and show either flat tops or circular dish tops. FME also lists 1.576" as the CH for the LA 360 pistons. (Sealed Power 405 pistons, with the circular dish.)
