The heads might be nice but for the cost of all the custom fabrication required you could likely get something much cooler. It might be something neat to play with some day when I'm old, rich, and bored.

Try http://www.valleyhead.com/ sat down with the owner a few months ago about some other machine work and he had a beautiful 32v setup he manufactures himself, IMO much nicer then the Arao.
If you go Arao, get a CNC piece if you can, the handported pieces I saw last time I was by there looked pretty
They suposedly make some pretty sick power with minimal cam timing.

You may have to shoot him a message on the contact page to get a link. The motor that I saw in his shop was
Not sure if the L98 manifold would work or not.

However, I probably could pick up a Z for the price of the engine swap.

I asked for some references. I wanted to TALK to someone who actually had them on their cars and what they were experiencing....no reply from Arao. Sent them multiple emails...talked to them on the phone...promised they would email them and still..
..nothing. Either nobody WANTED to talk...or they couldn't find anyone that had good experiences on a street-driven motor.I went with Brodix T1 M2's instead. Won't make as much power...but still a rather straightforward install. You can get similar flow numbers from some 18 deg. or 12 deg. heads as the Arao, but you have all kinds of accesory, header & intake issues to work through then.

I too looked at these heads. I came to the same conclusion that Joe90 came to. If they worked as good as they claim, you would see more cars running them. 8k for a set of heads is expensive, but for that performance they claim, you would see more of them out there, cause its really not that much money when you figure it all out. over 430cfm in a sbc head would be incredible for power - and would be the hot ticket for racers everywhere.
I believe they are overrating their stuff. Could be wrong, but what Joe experienced is probably why he did not get a reply. They would have happily given out names, since as I always say the proof is in the pudding.

If you do a search on camaroz28.com you will find quite a bit of discussion of these heads over the years.
Currently there is a guy over there who has a set and is paying Brett Baur "whatever it takes" to reengineer them to make them work.
