Long story short, im top-swapping, I've brought 5 sets of heads to the machine shop to get checked out and have a valve job done (great deal, family friend) Each and every one of them were cracked between the valve seats, and the most recent set I bought from a local member were just incredibly f'd up...Now I'm at the point that it would have been cheaper to just get ZZP's reconditioned heads for $250. I've read that many people run anyways when the cracks are small, but I have worries with the slightly higher compression.
Pros to running the cracked ones: I can use the $250 that I would be spending on ZZP's heads towards 1.9's instead; and maybe I'll be lucky and not have a problem
Cons: I'll end up having problems after getting it back together and have to start all over again.
FWIW the machinist said that the cracks on one set were extremely small, but still there.
I'd like to hear from people who have actually ran cracked heads, or know someone who has. Hopefully then I can make a decision on what to do.
