LS Valve Cover Differences
I am trying to research the differences in the factory valve covers and their available threaded mounting points
I have searched the forum and Google trying to find the information with no luck
Trying to find the information to the differences in mounting locations on the factory valve covers:
• Which motors have the same covers
• Car valve covers different than truck motor covers etc..
• Maybe it’s a Gen III vs Gen IV difference?
Specifically I’m trying to figure out the front lower mounting hole on the passenger side cover…what is it for? Doesn’t seem to be for the coil brackets, and which motors did it come on and not come on
I’m finding that sometimes it there and sometimes it’s not, but I can’t find specifically why or why not
Thanks for the help and any advice offered

Possibly for different coil covers? Vettes, TBSS, GTO, CTS-V, Escalade, etc. had pretty covers whereas the typical truck just had the center Vortec cover. Seems like I recall seeing ball studs screwed in there for those covers to snap onto. The 05 Vette valve covers I looked at yesterday on my LS2 have that hole..nothing in it because it was stripped to a long block.

Look at the underside of the cover in this link.. Related to the position of the hole for the filler it might line up?

I was just at a point of I don't know what other terms to google to figure it out.
So with that logic the early LS1's in early 4ths gens wouldn't have had those mounting studs because they didnt have the plastic coil covers
Factory Plastic coil cover engines = have that stud
Early motors/LSA with out plastic engine covers = dont have that stud
