Have a look here, seems like there were several different possibilities in 68/69

I guess I need to make my question more clear. I'm not looking for the correct valve covers for my '68. I'm going for a restomod. I'm thinking some of the parts coming off the '68 would be helpful to the purest group for restorations. I don't want to post for sale a part that is misrepresented.

If it makes it easier, then post a pic of your valve covers. It’s easier to look at the covers and tell you what you have versus explaining the differences between Corvette covers and passenger car BB covers. That way I can tell you what you have. There are differences.

You were clear. If you read through the post Mooser posted it explains what a Corvette valve cover looks like.

Quoting PJO from that thread I linked
There were four different designs for 427 valve covers used during 1968 and 1969 production
The first design is a chromed carry over of the1967 427-valve cover with two clips on the intake side of the cover and a tapered rear. The driver's side valve cover has a large depression or crunched area on the lower rear corner for power brake booster clearance
The second design appeared around January 1968. On the passenger's side the L bracket is moved from its center position 3 inches backward to line up with the crankcase breather opening. On the driver's side, the large depression for the power brake canister is deleted and the end tapers evenly with a 60 0 slope from the intake to the exhaust side of the rear of the cover. To compensate for the taper, there is a thumb-size clearance bump next to the spark plug wire bracket. This allows for the continued use of the drip rail and contains the end of the drip rail and its projection weld. In addition, the two clips are removed from the intake side of the cover and as single clip appears on the exhaust side near the center of the valve cover. The clip is partially coated with black plastic material
The third design appeared around July 1969 and is identical to the second design except that the tall bent bracket with a tang that support the driver's side spark plug wires is moved forward about two inches, placing it forward of the rear intake attaching bolt
The fourth design appeared around December 1969. It is identical to the third design except that the clearance bump for the end of the dripper rail is removed. The projections of the dripper rail welds remain
Seems to match the second design 69 cover
