Jezzma:

From the piston picture it appears that you have retained the original compression height and wrist pin diameter.
Given that, rather than having custom con rods also made, it may be to your economic advantage to simply clean up the original rods with beam polishing and removal of the balancing pads to the extent possible. The additional weight of the wider big end of the rod will not be a disadvantage for a street engine.

Had you selected an off-the-shelf aftermarket con rod of 5.4"(~137mm) length w/ 48mm bearing, then the pistons could have been made for that combination of compression height and pin diameter.
