OK. Well I measured the exhaust valve tops and they appear to be the same, or at least close using a standard tape measure since my engineers rule doesn't exist. So I pulled a rocker arm from the donor motor which was easy enough. And then I pulled the damaged one from the good motor.

It sure looks like the damage was man made instead of normal wear and tear, but I'm no expert and I don't want to dwell on the why.
When I pulled the push-rod to check for damage as well as to see if it was bent, but it didn't want to pass through the hole and once it did I heard something fall inside the block dang

I pulled the side cover and discovered that the motor has hydraulic lifters and the keeper is missing from this one allowing the lifter to come apart when I pulled the push-rod.

If this motor has hydraulic lifters then it must be from a car.....Correct? ohwell
The stamp on the block behind the distributor says.....F 11 30 B

My questions are:
can I use the lifter with out the keeper or do I need a new lifter?
How do I adjust the Valves after I put it all back together?

Any help would be greatly appreciated
