From my bench last Friday.... New head, ootb, stealth valves
and valve job. 4.375 bore, 28" test pressure;

Lift........ In/ex
.100----65/50
.200---144/104
.300---207/139
.400---235/168
.500---247/183
.600---250/192
.700---253/197

I've had a few sets of these come through the shop over the
past few years, and on my bench, mid-250's on the intake is
pretty typical for them in ootb form.
