Plumbing coolant to center freeze plug

I was reading through the cooling mods thread that was written by a guy who went by sanborn on another mopar page where he talked about running fresh coolant to the center freeze plug to help cool the center exhaust ports. I have made some plugs to do just this, but now that i have the turbo headers on the motor i have no room for these plugs and elbows. My question is would it still be worth my time to install them in the front or rear holes instead?
