Q :What
is the main advantage of running your 2v heads over
my ported factory 2v heads?
A: There
are many advantages,firstly the throttle response is
improved noticable, not only will you see a peak torque
increase,but it will be surprisingly broad compared
to what the iron 2v heads can deliver.Also the fuel
economy is much improved and not to forget,the weight
saving is quite large.

Q; Which head bolts or studs are
required? I ask this because the other brand of heads
require costly custom studs just to bolt them on correctly.
A; Just normal cleveland style
head bolts or stud kits that ARP list for a 351 cleveland.Nothing
different at all,you can use your exsisting ones if
they are up to it and are in as new condition.

Q:
Which of your cylinder heads will best suit my engine
combo to allow me to achieve my goals?
A: The correct choice depends on the capacity of your
engine and how much rpm you would like it to make
power to.
As a general rule of thumb a 351 cubed engine will
make power to 7000rpm using our 2v cyllinder heads,
more capacity or rpm will bring our larger runner
cylinder heads into consideration.
I would suggest getting in touch with us so we can
recommend a suitable cylinder head combination that
will best serve your needs.

Q:
What head torque settings do you
recommend with your heads?
A: Follow normal torque
settings,our castings are heat treated properly and
achieve the full T6 specs,so altering the tension is
not required.
|
Q:
Do your heads take the normal
spark plugs?
A: No they don't.Like all good
aftermarket cylinder heads they require a long reach
5/8 hex washer seat type plug like the NGK BCP6ES range,never
use a tapered seat plug in alloy heads,you will damage
them trying to get them out as the taper locks onto
the alloy once it goes threw a heat cylcle.
|
Q:
What length pushrods are required?
A: Pushrod length may and
most likely will differ as camshaft base circle, lifter
length,block decks or cylinder head surfacing or valve
tip length can all alter the required pushrod length.It
is not at all uncommon to need a different length pushrod
for intake and exhaust.We recommend checking pushrod
requirements on pre or final assembly.
|
Q:Why
should someone purchase AFD over your competitors?
A: Hear at AFD,all the
design work is done by AFD's owner,a renouned porter
of some 20 years exprerience and has a real passion
for Ford cylinder heads and the overall expense of fitting
them is always a major consideration in the design process.Things
like keeping the exhaust port in a as close to stock
location and being able to use pretty much everything
from your existing cleveland whilst producing never
seen before performance results from a cylinder head
that retains all of those factory type layouts.This
all equates to less expense and more performance from
an AFD product.I don't think any of our competitiors
can even think of laying claim to that. |
