I haven't put a mechanical dial gauge on the oil pressure, but there
is plenty of flow at idle. Enough that I have to use valve covers
with the tops removed to keep oil from pouring out of the back corner
of the heads at idle. The dash gauge shows an increase in oil
pressure when the rpms is raised, so I am assuming that the pressure
is fine there as well. The rockers are torqued to 21 ft-lbs and have
been verified by two different torque wrenches. The lifters are brand
new stock replacement roller lifters with about 500 miles on them now.
