Default Heads-problem??

I recently bought a pair of 1.94 heads. All of the intake valves have scuffs on them where they collided with the pistons. They look newly refurbished before the incident. Is there anything besides replacing the valves I should be looking for in terms of damage?
Thanks, Rick

Since you didn't say you knew that real history of them, I would have a known competent machine shop look at them. A valve could have a miniscule bend, a guide could be shifted. The head could even have hairline crack. Be safe and not sorry. Dennis

Thanks, half of most of the intakes have a blue tint to them also. What might that mean? Are they bent?

It's not done much anymore but five minutes each with some valve lapping compound and you can tell for certain if a valve is bent.
