Is JB Weld good enough to repair a chipped/cracked cylinder head?
no it wont work anyone that knows anything about cars should not have given you some of these answers you can not repair a cracked head with anything you cant weld it or use jb weld it is trash you need a new head the only thing this one is good for is a paper weight you can pick one up at a junkyard cheap take it to a machine shop and have it reworked it will be best to do both sides not just one
