When does money outweigh sentimental value? 1968 notchback build thread

Looks awesome! Benefit to the cooling lines? Cooler coolant running outside?

Cold coolant entering front and rear of the block, instead of just the front. This should, in theory, cool the block more efficiently. I'm also routing coolant from the rear of the intake up to the thermostat. That should stop boiling off at the rear of the heads.
