As these are Australian designed and made heads it is only natural to assume that the Aussie magazines will be the first the review them.
Here are 4 articles from the performance and Hot Rod/Street Machine magazines on these heads. Each document file is around 100kb so they may take a little while to load on a dialup connection. They will open in a new window, simple close the window when you are finished.
Please note all prices in the articles are Australian and not relative to this auction. AFD phone numbers are listed in the articles. If you feel the need to call AFD for additional information please do so.

This engine was put into an every day driven car weighing 3450lbs, auto trans, 4700 rpm stall converter, 4.11:1 gears, street radial tires and full exhaust system and so far has run 11.80 sec @ 115 mph with wheel spin off the line. This simple combo is easily good for a 10 second pass.
Q: Is there any shipping charge?
A: No, the price includes shipping to your door (Lower 48).
Q: Do you offer a other CC chambers?
A: Yes we do, please ask for details!
Q: Do you offer a 4V Alloy head?
A: Absolutely! Ask for details.
Q: What cam do you suggest?
A: I don't have any specific cam preferences. Most of the cams available off the shelf or catalogue have to much exhaust duration for these heads, they are best used with 6 degrees more on the exhaust than the intake and ground on a 108 lobe center separation angle. After ordering we can recommend a cam once we know: Engine capacity, Fuel rating, Compression ratio, Transmission/gearbox, Differential ratio/tire diameter, Intake manifold
RPM range required, Header diameter.
Q: Can we call you?
A: 503-804-3117 10am - 10pm PACIFIC
Q: Can I use dome or pop up pistons.
A: The pop up pistons can be used, but some reshaping of the dome will be required. Originally they were designed for a flat top piston. Before deciding on a pop up pistons I would advise that chambers be cut down to low 50cc's before piston to valve clearance becomes an issue. This would result in over 12:1 compression ratio. Much better flame travel with flat top pistons.
Q: Can I use these on my Windsor Block (Clevor).
A: Yes, in fact we will supply the heads to you with the Clevor modifications already completed. Ask for details.
Q: What is I want to run a blower or turbo, can you supply larger chambers?.
A: Yes we can. Ask for details.
Q: What cars can run these heads?
A: Any vehicle that has a 351 2v, small block Ford, 351-c 4/v, 400 4bbl, Aussie 351C or 302C, 351w 2/v, 400m 2bbl, 351-w or a 4v 400-m.
