I've got a Kaiser housing and the car does take a lot longer to warm up than it did with the original factory-fitted thermostat. I think there may be a difference in spec between Kaiser's stat and the original MGR one.

With the new stat, it takes about 3 miles* more driving to reach normal running temp (according to horizontal bar on the dashboard gauge) hence the heater takes longer to warm the cabin up. Mind you, these heaters aren't exactly quick anyway.

Edit: *

Original stat: normal running temp reached in 1.0 to 1.5 miles.
Kaiser stat - normal running temp reached in 4.5 to 5.0 miles.
