Cracks in head

My heads were magnafluxed at the machine shop and they have two cylinders have cracks going from the intake valve to the glow plug hole. That's a very small area there. They were pressure checked and were fine. After all the reading I've done this seems to be somewhat of a common crack. Im putting the heads back on the truck as I don't think its going to be an issue and I can't afford new heads right now.

Does anyone have experience with this?

I think I would look for a solid used core. Sorry don't have anything more to add than consulting with the guys on Nation and Army.

In my eyes they are probably fine to run for now but I would be looking for a good core. Those cracks could get bigger and bigger over time and cause some real issues.

I think you're on the right path. Just don't stress the old ones too much and start getting some new ones to take their place ASAP.

i would look into deburring valve seats. i think there was a discussion on the other forums abput this. apparently deburring can prevent cracking more than just hardened valve seats. when i get on a computer ill try to look it up for you.
