Why doesn't the HSR have the rear crossover coolant passage?
And is this going to be a cooling problem?

I did a search now and read that (apparently) the lack of a rear coolant cross-over is not critical.
And I checked the Accel base that I just removed, it does have the rear cross-over, as the factory intake has.
