+1 .A "concours restoration" is a broad question that can mean different things to different people. This is because there are different classes with different expectations . With that said If we can't see it we can't judge it. We don't check cams for factory specs or for hipo counter balance ether. I can't imagine someone asking the question of does it have a 10 1/2 clutch and pressure plate in a concours venue. In the very unlikely situation that concours judge or enthusiast asks the question and you don't have the assemblyline assembly I would plead the fifth if you don't want the possible negative consequences. 
Ok, these are good guidelines and answers for me. I bought this car in the spring. It's a excellent driver with #'s matching driveline, pretty good body, and very good documentation going back to the original owner. It is not concours by any means but as I do my repairs I want to return it, where practical, to original/concours condition. I am making the car mine, with no intention on entering it into concours events. In other words, some changes I will make as original, some will be modern improvements. But if I decide I want to make a change to original, I'll come here for guidance. Hope that makes sense and fits in with the intent of the forum.
