Thanks! I also hate the appearance of worm drive hose clamps. On the LA engine, I had put heat shrink on them and painted them black to mask the ugly.
I've never used them, but that's what I intend to use on the heater hoses since both ends have a threaded fitting for removal.
I'm going to use t-bolt clamps for the radiator hoses. I just need to be careful tightening those because they will crush the aluminum inlet/outlet on the radiator if overtightened.
