Cannot comment on longevity of a performance rad heater core yet, but warms up my hole filled cab great. Before replacing mine I had never torn apart a dash nevermind doing a heater core. Took me 4 hrs and was very simple. I keep a heater core hose connector on hand for longer drives in case of a failure, cheap insurance.
I carry a bypass hose as well.
