Intake valley pan

Right out of the Milodon catalog:
LIFTER VALLEY BAFFLE
Keeps hot oil off the intake manifold, allowing a cooler fuel
mix making more power. Keeps surplus oil out of valve covers
leaving more in the oil pan. Maintains oil pressure, during
pushrod or rocker arm failure by keeping lifters in their bores,
except with roller cams.
