One of the biggest issues is with the lifters and oil galleys that feed the top end. Early lifters will starve the top end of oil. Another issue is the early heads only used 15 bolt heads and the later ones used 18 bolt heads.
Your best bet is to find the serial number AND build date on your block and get the correct parts. | | |
