OK, I believe that you can use the J13 exhaust/intake manifolds, it has better exhaust flow characteristics, and it gets rid of the leaky exhaust collar, I have the same issue as you do on my U320, it leaks bad, but I have alternatives now if I want to use them.
I bought the "Patriot/exhaust header(H4800-1) from AutoZone that would likely work for you, but it would mean that you needed to use a different intake manifold or just live with the intake suspended in the air if that's possible without hitting the header.

I actually have a couple different exhaust manifolds that will work on the E1 I believe, I bought them for future use, I do not have a stock MGB exhaust manifold.
I also have a couple dual SU setups that I believe will also work.
Here is the pierce intake manifold that can be used with that header above if the stock intake will not work, I have a couple of these new, you don't need to buy one, I'll sell you one for cheap, they are made for a Weber though.
Here is the exhaust manifold from a early high performance MGB GT, I do not believe that this will work with a column shift or maybe not even on a LHD truck.
Here is one of the dual SU setups, I will trash the air filter housings.
Here is the other dual SU setup I have, it shows the linkages better.
Here is another intake manifold I bought for cheap, Datsun SUs bolt right on these manifolds, but the linkage would likely have to be custom made.
I have not mounted any of these parts yet, but they measure out correctly, not sure about steering column clearances yet, but they should bolt right on if they clear everything, they are early MGB parts which the E1 is a copy of.

Not at all for the exhaust. Though the 1 1/2 inch down pipe is a copy of the 1 1/4 inch. I picked up a NOS pipe from eBay, but reluctant to use it as I would like to keep it to make copies - if I can ever find a shop that will make me an 1 1/4 exhaust system - bike shops around here have not had many kind words when I tell them what I would like.
