Intake/exhaust manifold nut trouble

And before you say "but the Offenhauser intake is different", you're right, it is different. You have LESS room with the Offenhauser than with the stock intake, but even so, the socket goes right on it. I've done literally hundreds of these through the years both in and out of the car and it's not difficult at all. I'll admit, it's not as easy as some, but I can have the manifold set off and back on with new gaskets in less than an hour in the car as long as no bolts or studs break.
