You'd need 4 of them, probably what are similar to the 4.6 32v

are you sure that they dont just use a special rocker arm? one that splits off onto the 2 valves or something? How would you convert a cam in block motor to over head cam?

they gurantee some big numbers...... mmm i wish they actually had a dyno video or something....

well 4 valve heads are supposed to increase volumetric efficency immensely. like 10% or so, so i believe it. Look what they for hondas, and the cobra motors. Most of the really high horsepower motors nowadays come with 4 valves per cylinder.

You need to read the site:

....one pushrod operates 2 exhaust valves simultaneously. Rocker arms ride on needle bearings and are shaft mounted, similar to Chrysler Hemi rockers. One pushrod operates both valves simultaneously with individual adjusting screws for each valve.
