Neal,
On all my personal engines and engine builds I always block the heat
crossover passage to prevent superheating the plenum which causes cracks over
time in cast iron manifolds and can pose the same problem in aluminum
intakes. Second reason is to prevent superheating the plenum to increase
power – factory designed this for easy startup in cold weather. Our winter
temps are teens, twenties and thirties and I never run a choke and always block
the heat crossover; no issues at all in any of my engines and one has been
performing admirably for thirty years.

Subject: blocking heat crossover What are u guys doing with heat crossover, blocked or open? Moderate
winters where i live, typically 30s or 40s at worst, rarely below 30. Just
wondering before I swap manifold to eddy performer.
