Yeah I am trying to decide for the next round on my 340 if I should keep the stock stroke or go stroker. What I like about the Indy heads is they are iron which helps give more of a stock appearance, plus I don't like the overhang on the ends of the block you get with aluminum heads. I was just reading about how hughes modifies the indy heads and those look appealing. Also I plan to retain the 6 pack, so that limits head choices as well.
