Description
These
are
the
highest
quality
and
strongest
Head
Studs
available
on
the
market.
We
would
recommend
these
for
anyone
looking
to
build
their
VR38
motor.
Consider
these
an
insurance
policy
for
your
head
gasket...
If
you're
looking
to
make
big
power
(proven
over
1000+whp)
but
don't
like
the
idea
of
lifting
your
cylinder
head
and
replacing
head
gaskets
frequently
these
are
exactly
what
you
need!
These
studs
are
manufactured
specifically
for
us
by
A1
Technologies
and
utilize
an
H11
material
that
is
much
stronger
than
the
typical
8740
chromoly
and
yields
a
tensile
strength
of
260,000
psi.
They
are
also
provisioned
with
a
hex
broach
on
the
top
of
the
stud
enabling
you
to
install
them
with
the
cylinder
head
on
the
car
if
necessary.
What
is
so
different
about
these
head
studs?
At
first
glance
these
may
appear
to
be
similar
to
the
other
ARP
and
A1
Technologies
head
studs
available
on
the
market,
but
that
is
simply
not
the
case.
The
MAP
Ultimate
Duty
Head
Studs
include
an
additional
feature
known
as
a
"dog
point"
(shown
below)
that
seats
the
stud
in
the
block
and
preloads
the
fastener
for
an
accurate
and
repeatable
torque
sequence..
