318 cylinder heads 302 casting and 714

[snowmobiler7c]

I just bought a 90 318 with plans to use the heads on my 70 dart. Once i have taken it apart i notice they are not 302casting and are 714 casting and looks like they oil through the pushrods like a magnum motor. But they still have the heart shaped combustion chamber. Most articles i read said the 302 heads ran from 85-91. How do these 714 castings compare?? thanks

Do they have shafts or rocker stands like a chev?

If they ahve shafts you have a magnum, also, if the intake bolts are sideways into the heads, you have an LA< magnums pull the intake straight down.

Not sure on magnum casting umbers but I suspect you have a magnum.

Magnums have stud mounted rockers, not shaft. Besides the 302, I think the only closed chamber LA heads were used on 273's. Maybe not the original heads? How many valve cover screws? A picture would be helpful.
