I friend was going through his shed and gave me a box of car parts that were there when he moved in. When I went through the box I came across number 2 and 3 Billet mains for our motors. However they are four bolt splayed.

Can we use these on our stock blocks or can the only be used on aluminum and stage blocks? If we can use them on our stock blocks what machining if any do we have to have done? Thanks in advance to all who help!
 
If the center 2 bolt holes are straight up and down then you could cut the ears off and use them in a stock block, but the cost of machining them may not be worth it.
