if you are looking for a good rebilt motor best thang is to go to autozone or avanced auto or a known place to get the motor cheep and if you are raceing it go big and get the best and if you are looking for an ok one and you wount to do it right go start from the block and work up when you rebild or biy new. do not use the old head if you have not gotten it checked out because you have ran it dry the motor got hot and may have worped the head
so best off do it all right dont cut corners
