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?

most cars have that head design its really not that special.

I know that, but i just never noticed it.

No, as far as I know, its not a hemi-style head. Just cause the spark plugs are like that, doesnt necessarily mean its a hemi head.

That is what my major question is really? With the overhead cams i just didnt know.

The hemi in those motors has nothing to do with the heads. They get the name because the piston tops are round or hemispherical.

Then it would have a little something to do with the heads then.

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.
