4.6 4v question
I was just looking at pics in my 5.0 magazine and i noticed the plugs are in the valve covers of the 4.6 cammer. I know on the old cars the hemi engines are recognizable by the spark plugs in the valve covers....so does that mean the 4.6 cammer has a hemispheric head design?

The heads are almost the same. just bigger i believe. The pistons are himispherical so the cams can drop the intake/exhaust valves lower into the combustion champer to create more air flow. If they weren't the pistons would knock with the valves equaling one very sick engine.
