Compression test
I did a compression test today and found 2 cylinders with 30 to 60 compression which is very bad. The car isn't worth 5 -6 thousand it would cost for a overhaul so I may look for a used engine replacement or any less costly solution to this issue.

Cam shaft, Do you think this is a top end problem?

Compression test - update
Can this be done by just removing valve cover?

Yes, you can check the camshafts for wear by removing the valve covers, and yes, worn cam lobes can cause low compression.
Checking the camshafts is a hell of a lot easier than replacing the engine, and it doesn't cost anything except for a few hours of your time.

Easy to check the cams on a M116 or M117. I just did the whole oiler tube cleaning/parts replacement last night in 1.5 hours...and I'd never worked on a v8 before other than an oil change.
