I will say i do not know how the originals were made back in the day so i can only tell you about my experiences about todays knock offs. I expect That when I order reproduction products I'm going to have to do some refitting because they just don't fit right. My experience with the Fenton headers and intake I had to do some modifications to them also. I thought they would match right up to my 235 head However At the ends of the heads I had to build a bracket Because the Fenton headers Mounting tab was a lot higher than the one on the intake. Now in all fairness Don't know who is really at fault. I bought the intake from Patrick's And the headers of ebay. Wasn't a big deal I figured I'd do some work on it anyway. Now the thing that really shock to me The intake from Patrick's that I bought I did not notice it until after I had it power coated When I set it down on the table and I noticed that the ports were not at the same height I looked online and looked at other intakes already installed in the motors and they all seem to the lean to the front of the motor maybe it's designed that way but I would think that it would level. As far as mounting the two Fentons to the head i just made it work. And if it's wrong I will go back and find out what's wrong and make it work.
But you guys are right it doesn't matter what body panel or what engine part and knock off it should be right.
Secondly one of the stoveboulders who lives in Germany bought his Fenton intake from Patrick's and when he got it home. He noticed that there was a hole in one of the intake ports he sent me the picture of it and it looked like you could have dropped a dime into it luckily he was able to to weld it and repair it.
