Cracked head? Use it or get another
So I bought a 98 Cherokee with a blown up head gasket. Pulled the head and took it to the machine shop. He skimmed it and magnafluxed it and found a tiny Crack on one of the water jackets between the 3rd and 4th cylinder. It goes straight down to the opposite water jacket so we decided to drill the end of the Crack and he said I shouldn't have a problem with it. Took it back to my shop and got bored so I took one of our little cameras that are meant to go down into engines and I used it to look inside. I'm pretty I found two more cracks inside the actual head.
What do you all think? Run it or get another reman head. Who's a reputable place to get another 0630 head from?

$450 for a new head really isn't a bad deal. I only paid $250 for the Jeep so I think that's what I'm going to go with. Should have done it from the get go instead of having it machined for 140..

How long did it have "a blown up head gasket"?
Did you perform a compression and or leak down test before you tore in to it?
Is there a milkshake in the oil pan?
If so it's silly to waste any money on a cylinder head when it needs an engine.

Good compression, no coolant intrusion. Headgasket had began to split but never completely separated so there was more gas in the coolant. Lower end is perfect with only 147k on it.
