piston install orientation

Hi guys,

Finally starting to put everything together now. I have some simple orientation questions so I don't install things wrong.

I read in other posts that the connecting rod tangs face the outside of the block and the big end chamfer faces the side of the crank journal, not the other rod that shares the journal. Good

But how about the pistons? The picture below is the piston I will be using. (SRP inverted dome part #138103 for a 383)
In the picture below does the 'A side' face the outside of the block and the 'B side' face the lifter valley?

I would put the B side to the outside of the block too. Also I don't know about the inverted dome pistons but just check that there isn't a left and right piston. Meaning that the valve reliefs are different sizes for intake and exhaust. This is because the valves alternate on the small block. Exhaust intake, then intake exhaust. Does this make sense, maybe someone else can word it better.
