360 HP Confusion. History of this motor?

Brooks James said

I did some research, this is not what I believe necessarily

Windage tray
Oil mods
Chrome caps in valve stems
Undersize special exhaust valves
Special intake valve
Special valve springs
Hemi style rocker arms
Double roller chain
Special carb
Special distributor
W2 heads
6 qt pan

Etc etc etc

WTF, is there an authority here ???

No "oil mods", stock block and passages.
No valve caps.
Valve rotator delete- therefore different valves and springs were used, also to compliment the updated spec. 340 style cam.
"Hemi style rocker arms"? No such thing, unless you're referring to 273/340 6bbl. rockers. But those never came on E58s either.
W2 heads NEVER came on ANY production line engine.
The E58s were assembled by the Chrysler Industrial/Marine division, as were most all performance oriented engines at that time.
