/6 198 rods needed badly

Hi everyone, Charged225 here. My Duster is a /6 225 turbocharged, I am in desperate need of a set of 198 connecting rods so i can run modern piston. I am having a huge blow by issue because of the old pistons/rings. I am from Riverside, Ca. My Duster usually is my daily driver and i want to start running the boost a little higher. The motor with stock compression ratio will be able to run nearly 20 lbs without any mods; however I have a boost retard ignition and a water pump that kicks on after 5 lbs so it is very bulletproof (pistons beign the last hurdle).

thanks,
Charged225
