I have a 289 that I was porting the heads on but they need a total rework and they are not worth it. I have a chance to get soem edelbrock rpm's for a good price and need to know what I need to put them on. The are rpm's with 190's, crane gold 1.6 roller rockers, locwire gaskets, 7000 miles. I know hardened pushrods, what else?
