I'm looking into putting 1.6 ratio roller rockers in my 305 (5.0) TPI. What brand and what kind should I be looking for. I know that they have to be self aligning, is that correct? Will I have to butcher my valve covers to get them to fit? If so, It's alright, I've got a set of "pretty boy" chrome Hearbeat covers I've been dying to put on for over two years now. So...basically I need all the information I can get about some rockers, any kind of machining (god, I hope there is none), etc. Thanks to anyone and everyone who can help me out!

 

Look in Summit or Jegs for Crane Gold Rockers, they're expensive, but its what people suggest.
