Reply to "Cleveland 4V Heads"

The spoons are usually called 'port plates' and apparently do help on non-racing cars. Several shops sell them. If you were satisfied with your Pantera before, use the heads you have and add an Edelbrock 'Performer' 2V intake with your present carb. Or, use 351C 2V heads available at any wrecking yard dirt-cheap. The same intake will work for both 2V and 4V heads. A 2V intake mismatched onto 4V heads will vastly improve your low end acceleration & 'drive- ability' as well as mileage but will fall flat on its face above 5200 rpm. The manifold mismatch acts just like port plates to increase low end air velocity. If, like me, your engine doesn't spend much time in the upper rev ranges any more, this is the cheapest street driving fix you can find. And its not as permanent nor as expensive as changing heads.
