I have some cracks in between my valves and they seem pretty deep. I was wondering how deep is to deep and what can a guy do to help the situation.
thanks

Not a concern unless you can fit a US nickel in there.
Posting a couple of pictures, if possible, might add some clarity as well.
i have a used head with no cracks. first time i saw that.
Same here, every one I've ever seen was cracked till I pulled the one I have in the pickup the other week for a headgasket, no cracks, looks new-ish. Factory reman maybe.
There used to be photo's of a cut-away showing how deep they could crack somewhere on one of the forums awhile back.
here is a pic
I recentley finished cleenin up the head and fould cracks in tge precups iv read its junk if the precups have cracks.
