I have an aluminum hemi head and I am not sure if it's a good head or average head or ???
Any help would be Appreciated on identifying them.
It is a Dual Plug, alum Hemi head, it has a number on it 3614433
and under that it has rev ? , I can't tell the last number but I am thinking it means a revision done on the head from the original design.
Also it has a DXSE 12 towards the lower valve cover rail between the valve and the rail. All the numbers are casted into the head.

All the port openings are square or retangle shaped.
Thanks For any info. I have a couple photos that I need to transfere from my phone yet.
Thanks David
