I understand the negatives of blocking off the egr passages, but how does a cm570 and 870 get proper coolant to the back of the block, neither have the rear egr cooler port?

Can't speak for 570 , but 870 doesn't need any and it doesn't have any negative effects on the cooling and pump . Not so with 871 . 871 definitely need one to have proper flow !!!
Rawze stressed on that many times and he is spot on .
