I have the new Edelbrock's. Blue thunder also makes a good set.
Here are the Edelbrock specs. from their site.

Performer RPM 460
Designed for 1968-87 429/460 Fords, these Performer RPM heads are ideal for high-performance street, drag racing and marine applications. These heads made over 500+ hp at 6500 rpm (+30 hp more than ported factory heads) and 525+ ft/lbs. of torque at 4500 rpm with the Performer RPM Total Power Package. Two combustion chamber sizes are available (75cc and 95cc) to offer a variety of compression ratio choices with engines of various size. Both of these heads match with Edelbrock Performer #2166 or Performer RPM #7166 for a proven combination. Intake ports can be opened up to match Victor manifolds #2965 and #2966. They accept factory exhaust, aftermarket headers and factory valvetrain components. Requires the use of 3/8" diameter pushrods. See chart for more specs.
