I purchased what I thought was a 460 ford truck engine (suppose to be a 1985 f250). The heads do no have the normal 5/6 bolt pattern around the outer edge for the Valvecovers, but have 4 bosses through the middle of the head which I believe are for valve cover mounting. What do I have or has someone really screwed up these heads??

 

Can you post a picture of it?

 

The only Ford engine that I know of with that type of valve cover mounting is the Y-block family, the 292 and 312:
