Ok, pulled the head off the son in laws 06 aveo, then pulled all the bent intake valves (it doesn't appear that any of the exhaust valves touched.....is that normal??). I had bought all the parts to repair the car.....except new valve guides. Every one of the guides is cracked.

Do I have to replace them, or can I get by just breaking out the cracked parts & letting it go as is?
thanks,
Mike Sal
