The
Alpha
GT-R
CNC
Race
Ported
Cylinder
Heads
are
the
most
developed
design
on
the
market.
After
countless
hours
of
testing
we
devised
a
port
design
that
offers
more
than
just
peak
flow
numbers.
And
by
utilizing
Computer
Numerical
Control
(CNC)
machining
processes,
every
cylinder
head
offers
consistent
and
proven
results.

The

Power
Band
Flow
bench
numbers
don't
always
tell
the
whole
story.
Most
vendors
just
state
their
peak
flow
at
max
lift.
Their
head
may
flow
270
CFM
at
.500
lift
but
what
about
flow
at
lower
lifts?
The
flow
at
low,
mid
and
high
lift
has
to
be
balanced
a
certain
way
to
achieve
the
most
effective
power
curve.

Top-Shelf

The
Alpha
Cylinder

utilize
the

Ferrea

components.
Their
valvetrain

are
made
from
exotic

Engineered
For
A
Better
Combustion
Seal
Through
our
rigorous
testing
program
we
identified
a
weakness
in
the
factory
cylinder
head
under
high
boost
conditions.
Our
Engineering
Team
developed
a
proprietary
modification
that
provides
a
better
combustion
seal
which
is
applied
to
every
