Raz,
I hope you will take some good advice.
1. See if there is someone close that regrinds camshafts and price their labor vs the cost of a new cam.You might have to research to get the original specs.
2. Install new lifters or have these reconditioned by a firm that knows how much convex surface theses lifters need.The surface has to be angled so the center of the lifter contacts the center of the cam lobe.
3. The naked eye or a bunch of friends will not be able to tell you how much wear is on these parts.
