340 heads

I am tring to figure out how to use the heads that came with my 340 when I got it. They are redone Xs, when they were rebuild for some reason or another they milled the rocker shaft mounting areas off I'm guessing to use roller rockers? Could I use these http://www.billetracingparts.com/W-2 Mopar Rocker Stands.html and stock rockers or would I have to go to a roller cam? If so what is the best rockers to use in a budget build?

Thanks, Kegan
