crooked valve stems?

[MassSupra89]

So I recently bought a remanufactured 7M head and the ends of some valves seem to be ground down crooked. It looks like someone took the tips to a grinding wheel or file and didn't get them straight.
What's the best way to grind these stem tips back to flat? Or should I just swap out the valves on my old head to this one?
Thanks.

Who was it remanufactured by?

Take the whole head to a shop and get it looked at.. and at the very least get them reground (if possible) if not, get new valves, or you will have a very shitty running car.

Already had it to the shop. Everything checked out good he just said the stem tips looked like they've been played with. Just small scratches on some tips making it unlevel.

Drew: I got it from someone local not a remanufacturer.

I'll try to get pics later, Just don't know if my camera will pick up such small detail, and I'm at work.

Might have ground the tips to avoid having to use new shims to set the valve lash.

Yea they're ground alittle crooked though. I just want to know if there's anything I can do to get the stem tips level again or if they need to be ground and chamfered, not looking forward to handing more money over to this machine shop again though haha.

The only way I know how to do this is by grinding valve tips with a tool post grinder in the lathe or other similar means.

To grind the tips of a valve square to the stem they need to be mounted in and cut on a valve grinding lathe.

Is the stem to guide clearance within specs?

 

[MassSupra89]

Stem to guide is in spec.
I'll probably be taking apart my other head and seeing which valves I can use out of that one.
