How do you seal a cracked head in a car?

I have cracked my car's head and need to fix it.

More than likely, you will have to purchase a new head. But you could try and put some radiator stop-leak in, that may temporarly fix it.

Replace it! trade the old one in at the wreckers and get a used one. Then figure out why it cracked, or you'll be replacing it again. A product to repair the head might be trusted to get you to the wreckers or repair shop.

A cracked heads can't be sealed. This requires re-welding the cast head witch is usually more costly and time consuming then simply installing a new head. The crack would have to be welded and then probably machined. Even if repaired it runs the risk of cracking again. So just pull the old one and install a new.

If you cracked a head in your engine, then its probably going to be cheaper to replace the entire engine rather than pay to take it apart.

They have a product sold at autozon and advance auto parts that says it fixes the crack in vehicle heads. However using this product is just a short term temporary fix since it will eventually crack larger causing you to need to replace the head. You can go to a junkyard and usually pick one up cheap.
