This is what I did to my factory rods, I also had them hone the small end and add an oiling hole for the pin so I could run the KB167s floating.
Cost me $360AUD including the cost of the ARP rod bolts - just over half the price of the scat rods quoted above. (Plus you would probably have an extra $200 in shipping & import tax on top of the purchase price on those)
I reckon the stock rods would be fine for what the OP is doing.
