273 questions...a few of them

Ok dropped by dads, had the vistation today and Easter at grammas, so it was a quick visit with dad. Here are some pics for reference, but this is what I noticed,
1. Old and new lifters are definitely solids, tried pushing down with a push rod...no go!!
2. Old and new lifters have same recess depth, put a push rod in each and they are the same. I didnt put verniers on them, just by eyeball, but bang on from what I can tell.
3. All the valves that are sitting higher are the exhaust valves.
4. Both the intake and exhaust valves have different #'s of grooves for the keeper.
5. New keepers from Comp were all the same, we could only use 1/2 the keepers from Comp.
6. Exhaust valves were the only ones to get the new keepers.
7. Pics of keepers, black one is new one from Comp, the one beside it has same amt of grooves, but you can see is smaller diameter.
8. Pic of rocker arm looks like it is real close to the valve spring???
9. Looked for cam card and there isnt one, just the specs on the outside of the box....I thought all new cams had a card??

So could there be issues with the keepers?? Maybe put the old ones back in?? We thought to put the new ones in as they match to the new springs and the black ring(whachamacallit) from Comp. I will post pics in a bit of the old and new keepers in the old spring topper.
