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?


Thanks!

Ok, 'A side' to the intake valley and 'B side' to the exhaust. Thanks!
(valve reliefs are the same size on the piston)


The rod bearings are Clevite 77H and are marked upper/lower. Another newbie question then... I assume 'lower' means the rod cap end, correct?

Thanks guys!
Phil
