This
High Port (HP) series design of cylinder head from
Airflow Dynamics Australia for the small block Ford
cleveland/Clevor/Boss type engine is the ultimate
in high flow cylinder head design. With all the
latest in high tech development from the top level
of motorsport designed into a high quality casting
made here in our home town of Melbourne,Australia
for the highest of quality control.
Each cylinder head has a custom valve seat design
to allow your engine to achieve all it can be.
With over 400 cfm of air passing threw the intake
port at a very low (.700" lift).
A smaller than normal cross sectional area for the
overall cfm,this makes this new HP
range of cylinder heads the most efficeint small
block Ford cylinder head of it's type.
Intake port height has been raised an additional
.450" from our Street Range SP4V series of
cylinder heads,the exhaust port has been raised
.400" from our exhaust port location in our
street SP4V series of cylinder heads.
In keeping the end customer in mind,we at AFD have
kept our normal valvetrain locations,so the use
of a readily available rocker system.(studs and
guide plates) can be used as a less expensive option.
