hemi ???

mister_hSeptember 18, 2007

Is Chrysler's current HEMI head on their 5.7L and 6.1L engine "really" different from that of today's other manufacturers' engines? I've looked at heads of several other engines, including Japanese and European origin, and their head (combustion chamber side) is more or less all hemispherical shape and the spark plug is at the center of each cylinder head. In fact, Chrysler's current design appears to be not a true hemispherical head engine; it has a polyspherical combustion chamber, but retains the Hemi's traditional inline perpendicular valves. I'm just wondering if Chrysler HEMI design has any special benefit only unique to them when comparing to other engines. Or is it just a advertisement gimmick these days?

I don't know nor remember the Hemi valve spring arrangement other than the intake/exhaust valves are not parallel as in the wedge head. Can you describe if it is any uniquely different from others?
