Air Flow Dynamics small block ford heads
AFD is a Australian company owed by David Webb.
These heads prove to be the most power producing heads for the $$.
These are not Procomp/ Speedmaster!
Procomp’s have a brass press in plug in the end.
All 4V heads work with any 4V intake manifolds.
The intake port of the head has a filled floor to reduce port volume.
You can either fill the bottom of a OEM 4V intake manifold port
or port out the bottom of the head if you want the port to
have an exact match.
Or buy the AFD 4V intake.
Exhaust port can use 2V or 4V headers
