From what I gather, the 915 J's aren't going to flow much different than the eddys once ported so I've gone ahead and bought them for $300. They are untouched from factory from a 71 360. Im in Australia and there aren't any machine shops that are familiar with what I need to do to them now to get them to their 90% potential so I need specifics to tetll my machinist exactly what to do to them. Thanks for the help! I'll post a new thread with this question to maybe get some different ideas.
