Max Lift???
what is the Maximum lift with these heads?
14096217...55-86...350..........Crate motor, 285hp/300hp, 64cc chambers,
72' or 90' center intake manifold bolt angles
with these upgrades. Looking to put them on the 327.
these are the 21 degree heads and have the 4 center bolt pattern for the valve covers.
the heads were rebuilt by a professional shop, and have:
5 angle valve grind
Crane valve springs with 110 pound seat pressure
Teflon valve seals
machined keepers
