Bypass hose for LA block with Magnum intake

I would think it cools better without it?

so are we going with...the 2 larger w.p orifaces into the face of the block over power the bypass and that the bypass actually can intake excessive pressure from the manifold.

Or the latter?

It's pushing out all holes, bypass just eases the pumping psi?

The bypass allows some circulation when the thermostat is closed, so actually reduces pressure. Also, if the thermostat fails closed, you still get at least some flow.
