Casa radiale head

Hi,
does anyone know if these come in regular lambretta piston profile and/or a flatter profile for the casa pistons?
I have just purchased one and the squish profile doesn't match the piston I have (AF wossner) as the head profile is much flatter than the piston(however it does look like it matches a wisco H2 piston I have knocking around)..
the dealer I purchased from (a well respected dealer, so I am inclined to trust them) says they have fitted many of these to TS1 motors with no issues, but given all the chatter on here regarding the correct squish profile I am not sure..
has anyone else had experience or insight in fitting radiale heads on non casa top ends?
