Re: Cracked head
Highly doubt it is a cracked head, but possible. Either way you will have to pull the heads off to do the gaskets so you might as well check for cracks and warp at the same time. I have a hard time keeping my SBC 350 cold some times. I am assuming you have already upgraded the radiator from the stock one?....

Re: Cracked head
Could be a lot of different things. When is it over heating and what have you done to diagnose it?
