Street motor chasing piston weight

Now i got the pistons down to 414 grams, and I will most likely have to reduce the dome to get quench clearance, so I´m close to the target 400 g, . It takes time to get those last grams, but there is no way around it when you are replacing pistons, and its more difficult when the assembly is initially balanced with extremely low reciprocating weight. Getting decent basic compression in a 4 3/4 stroke, 3 5/8 bore and bathtub type chambers is not doable with the typical 30 degree pistons,  but rather 43 degrees (dome) is required to get i.e 10, 5.
