I have the lo3 motor. For awhile I was looking for a cheap 350 to rebuild and drop in but now I kind a wanna keep the 305 and be a little different. Not many people bother with the 305, Especially the lo3. And I know why I've done all the research. I have an aftermarket intake manifold and a 2.5 exhaust with no cat, but now I need heads and a cam. I don't what heads I should be looking for. Any suggestions on which heads are best for a 305?
