The pic, though, makes it look like there are only 2 of those? Am I seeing that correctly?
Remember, I'm not the Porsche guy here, haha. But the few motorcycle motors that I'm referring to below, those caps are cast as one piece with the head, then split. That's a deviation from standard practice, in my experience though. Typically, the caps are cast, then machined, then bolted-on, then bored/honed. as one would expect.
?? go figger.

I believe the connecting rods on Corvette motors are single castings. They bore the hole for the crank, tap for the bolts and break them in half. It's pretty ingenious, considering you can't really bolt on mismatched caps in a rebuild. I'm sure that wasn't their concern, though. Most likely they found it a faster & cheaper process.
