Assuming you are 100% certain you have a recurrent intake leak:
Have the heads been off ever? Or milled? Are the surfaces where the seals hit still flat and true?
What air cleaner you running? The fitting of the backing plate can "pull" an intake and the manifold away enough to blow the seal(s).

I was just reading the latest engine labs about using the fuel. They also mention what it does to your oil. I don't know how to upload pictures from my phone on this site. But worth a read.

So, here it is a year after this whole thing started. Still having the same problem. I have also changed the MAP sensor. no change. Can't find any bad wires (yet). If it didn't run perfect, maybe I could find something to fix. Any suggestions ?

One guy I know who runs E85 has right around 15.0:1 compression.

well some good news at last. yes but i'm hesitant to reuse those lifters. 

It appears that 5/5 % gain is the number talked about in un-boosted apps .
I could see a huge downside would be keeping moisture out of the fuel.
Do you live in a humid climate ?
You would (should) likely need to flush the system with regular gas between rides .

Where the heck was that book when I was working on flat-rate

I think I could change a 6 speed cassette blindfolded in 6 hours LOL 🤣🤣

Don't know but I changed mine out of a carburetor model electra glide by going at it from the left side.  I remember it being tight but I was able to do it.  I believe the little screw was the biggest challenge not to drop it into oblivion.
