Take the valve cover off and see if the rockers have adjustable rocker arms. If they dont then its prob a 1981 or NEWER motor. If its a 1980 or OLDER i would use the head on your new motor if its in good shape... Quote: : : The slant 6 from my 68 dart is in the machine : shop with a spun bearing, worn head and : rockers.

Looks like they arent adjustable rockers. Can i use hydraulic lifters in my motor? Would i have to to use the head? Are there any design difrences that would make a later head more desireable, besides hard seats. I took the head off, it looks good except the water passages. Can these be cleaned up at the machine shop? Thanks Byron P.S. my 68 head is toast(needs alot of work). Quote: : : Take the valve cover off and see if the rockers : have adjustable rocker arms.
