255 ci V/8 pistons

[Anonymous]

I look for 255 ci V/8 pistons to put in my 250 ci, but Sealed Power (parts #478P20) indicate in its specifications : «Flat head w/4 valve reliefs».

Somebody how much measurement the 4 valve reliefs on this piston for cc :

Exist there another supplier for this pistons types except Sealed Power and Silvolite :

Thanks,
Wally

1.5cc total dish.
Any parts store or Napa online could order them, but there are only a couple manufacturers producing them.
