LZ23 Engine Build,Piston Crown, 89mm Wiseco Custom Pistons

The "dome" is actually a flat top with the balance of the piston area being recessed (16cc) for use with a closed chamber head. I sent Wiseco a sketch of the quench area of the head. They reproduced the flat top area to create the quench area under the head. These pistons are both right and left handed to accommodate the pairing of the larger intake valves in the head.
