Replacements for stock rockers.

I was looking at my rockers and noticed there are two wear marks on some of the rockers. When I pulled the head I noticed the shafts were installed wrong, both notches to front. One of the spacers had quit a bit of wear on the side. I am not to familiar with the stock rockers but I am worried about the wear and unknown previous history. I was thinking of the mancini rocker set:

It is a mild street build la 360, comp 262 cam, comp 901 springs, hydraulic lifters, speed pro pistons, j-heads. Just wondering if I should run stock, some new sealed power, mancini or the mp steels.
