I am using a 4.500 stroke x 4.500 bore with 572-13 indy heads and i need pistons.

I am using a 6.950 GRP rods and want to zero deck the block.I am not going to o-ring the heads so i will be taking enough off the block to get rid of the receiver grooves.

My main question is does anyone know of a set of off the shelve pistons that will work in this motor since i can deck the block down to the piston height.

Trying to stay away from custom pistons if possible.

Thanks in advance
