Pistons for A. Heads?

Can anyone tell me if these pistons are for A. Heads?





Any help is much appreaciated.

they look like a standard oem valve layout to me ........

here is a pic of my old weisco piston that had an extra flycut done to the because of the large cam





and then here is the pic of my new piston for my cj edelbrock

that double cut looks like one is for the oem , then cut for A460 or P51 . not for a bigger cam or valve

i dont know Dan but on the invoice for the machine shop they had to do the cut due to the block being deck and clearance for the cam .............. who knows ...that was on the old 521

unless you had a head that WASN'T Edelbrock or OEM, that shop took you for a good ride

yep they were the same edelbrocks i have on the new motor
