454 missing caps

I found two 454 2-bolt blocks over the weekend. Problem is, one is standard bore and missing all the main caps, the other is .030 over and missing the #4 main cap. Before or if I move on these I would like to know where to source the 2-bolt caps. I know they would have to be align bored or honed. Does converting to 4-bolt mains weaken the blocks? I thought about taking the caps off a 396 that's laying around. Was looking to use block in a 3/4 ton work truck.
