Ok, so fuel stand off. I've seen it, but never in a situation like this.
I'm thinking maybe try taking off the 2 inch spacers and see what that does for standoff.
If it helps, you are going the right direction. I don't have a standoff issue, but I am having some reversion issues (that is my working hypothesis at the moment) and I bought an anti shear plate to try and correct what may not be a problem.
I'll post some pictures of it and my intake in a bit. You just can't bolt them on. But it may be worth looking into.
