Agreed. The lifter in your photo is a milk bottle lifter. So solid lifter.
Any chance you can post the block casting number and head casting number. The reason I ask is that the vettes used a different casting then the regular production cars and they are very very rare. It may just be that you have a passenger car or truck motor in the vette as opposed to a real vette 235.
When I get home tonight I will drag out my 59 parts catalog and see what lifter is actually specified for the 54 vette.
