Default Is -16an big enough for rad lines?

Getting my setup back together and it's running pretty hot. Today was around 85 and while doing some tuning just putting around the parking lot it's holding 225-235 degrees. It's not ready to get out on the road yet but I'm not happy with those temps. I'm running the griffen rad, dual flex a lite pushers with -16an lines. I was assured that this would be plenty but I'm wondering if the -20an lines wouldn't help out. Car is a 408 with 91mm turbo.

You cant fit pullers? They work much better. 16an has been fine for me on a few builds but 20 an is better.

There is no room for pullers. Did a couple small things today and I'm gonna switch over to water/water wetter and see if it helps any. It looks like a -20 swap is in my future but I hate the thoughts of getting all new stuff. Anyone interested in a griffen rad with -16 bungs, stainless hoses and polish AMW waterpump with -16an fittings??? LOL

i run -16s on my setup and it never gets above 185*. I dont run a thermostat either, it just constantly circulates.

-16An should be plenty. That's moving alot of water. Probably more than the pump is capable of moving.
-16an is probably larger than most garden hoses? 1 inch, right?
I'd say you have to mess with your Fan setup. If the fans aren't shrouded, and are just mounted side by side, I would work on getting the entire core covered first. IMO...good luck.
