1966 Barracuda radiator shroud / cooling questions

I got the shroud in the mail and its really nice, going to clean it up a bit and throw some satin black epoxy paint on it.
Yesterday I flushed the whole cooling system, did new heater core hoses and a high flow 180 T-stat. She's running much cooler now, I think the T-stat did the trick. The new mixture I did with a bit more water, maybe 30% coolant instead of 50:50.

I got the restoration hose clamps to make everything pretty under the hood, dam those things are a pain. I didnt have the right pliers so used vice grips. Couldn't get the clamps on the short stumpy water pump hose so put the old clamps back on. Today I noticed the heater core hoses going into the firewall are leaking just a little little bit. Everything else seems good to go. I'll throw the shroud on after its painted. So far I'm happy and the engine is running much cooler.
