Hi,

Would have to beg to differ with you.
At AFD all the design work is done by AFD's owner. A renowned porter of some 20 years experience and has a real passion for Ford cylinder heads. 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 their competitors can even think of laying claim to that.

The dyno results supplied on www.airflowdynamics.com.au stand as a testimonial to their capability of making top shelf HP figures.
I would also like to mention the recent Boss 340 series of articles by www.mustang50magazine.com culminating in an impressive Dyno proven result of 598hp for a low compression, small cube street engine using the older version of the AFD heads. A smaller cam would have also increased the low-end torque as well as lowering the HP curve to make this an even more impressive result.

On a personal note, our company could have chosen to sell any brand of head we like, we chose AFD after exhaustive research on the company and their products. AFD won not just because of their superior product but also the back up service, extensive knowledge base and the cost effective usability.
