Engine Help identifying this Plastic Valve Cover/Engine/Head
So I have an engine in my newly acquired '85 CJ7 that I'm not sure what it came out of. The block code is 306C10 so I believe it's an '83 AMC 258 i6 / 4.2l . It also has a remanufactured tag to the left of the block code with some numbers that I can post if relevant. The head casting # is 8933002 and when I search for that it seems it's from a newer Jeep/AMC. The part number on the inside of the valve cover is 8933004109 and when I look that up i find an ebay listing for a valve cover for an AMC Eagle. This valve cover is slightly different from the other plastic ones I've seen on CJ's and YJ's. Those ones seem to have an extra couple small holes.
This one was leaking really bad which I assumed was the gasket but when I took it off I discovered cracks near almost all the mounting points, and the rear mounting point was cracked all the way through. I was wanting to identify this valve cover but I'm not even sure it's the correct one for the head. Seems like it might be a better idea to identify the head and get the appropriate cover based on the head casting numbers. Appreciative of any help.
