is something wrong with my valves? pics I am adding some 243's (stock) from a '05 GTO, new caddie lifters, and a cam (yet to be decided) along with some misc. stuff to my 2000 T/A. I pulled the valves and cleaned the 243's when I looked at a couple of the exhaust valves and this is what I saw: this is on the exhaust only. It looks like the tips are cracked.
This what 4 of the valves look like. 1 on one head and 3 on the other. Are they still good? what do I do?
Do I get new exhaust valves? I also need new valve guide seals for 243's what is the part#?
Thanks

Its hard to tell on my computer but if thats a crack around the stem do not reuse them. Valves are too cheap to risk it. Get you some new ones and inspect the rest of them closely.

That looks like retainer imprint, not crack, (difficult to say just by pic)
Also when you removed the valves did you mark them to go back in the same way they came out?
If not, time for a new valve job.

Thanks for the replies! Yes I did mark them. I can feel the "crack" with my finger nail. If i did replace the "cracked" ones should I replace all of the valves or just the (4) "cracked" ones?
Thanks again
Thanks again

If you're really worried, you could replace all of the valves. If you ask me, it's cheap peace of mind. Valves really aren't that expensive, I think when I priced out some new valves for my heads as a just-incase it was ~$200 for the new valves. That's all 16 of them.

the end of the stem is hardened, so that it doesnt mushroom over with the rocker arm pushing on it. (wow looks like i made that sound like a stoner joke lol)

Valves If you're looking for quality valves at affordable prices REV (Race Engine Valves) offers a quality street/strip stainless steel valve. www.revvalves.com
Patriot Performance also offers stainless steel valves at an affordable price. I've used both.

holy crap! mine don't look like that, but I guess if yours are that way and you are using them, them I guess mine are okay...When I took the head apart, I used a deep 3/4" socket and rubber mallet to remove the keepers. I thought because on some of them, only one keeper would jump out and the other would lodge in sidways, I did that to the top of the valve.
