what do you mean, aspects? Specifications? (specs?)
Do you know anything about what you need for your setup? length, material, type of lock grooves, etc...part numbers will depend on what you want to install...
I'm not sure on the stem diameter on the last part number; it doesn't define...bottom line is factory magnum stuff uses 8mm stems while LAs use .375"...
So there's 5.7 hemi or LS valves.
I'll measure some out tomorrow but I believe both are very close to being a drop in, with a valve job and proper stem height.
A Couple other things could be retainer locations and setting up proper spring installed heights.
The reason I say these 2 valves is they're cheap and very available.
