I have a friend who is using these from Edelbrock. With the stock hydraulic cam, they are as good as any.

They are not going to flow anywhere near what the Ford Motorsport A3 or C302 ported heads do, BUT if you are not going to run a complimentary camshaft with those heads, it won't matter.
The Edelbrocks will crispen up your street performance. They will be restrictive on a track though.
