Solid Cam, Use it or Not

2 lifters look convex, one concave, at least one lobe looks to be grooved and worn. Patterns on several lobes are suspicious. If it were mine I'd call Howards cams and start fresh. I'd rather spend the $300 now for cam and direct oil lifters rather than the $1000 and chipped paint plus a weeks work later. There's not much worse than getting sucked into false economy.
