I think you can go all the way to 87mm but that has to be pushing it.

I think the biggest problem at 87mm is headgasket sealing issues.

Is there any cylinder wall left between cylinders at 87mm? That has to be really pushing cylinder to cylinder spacing. I would not go bigger than 85mm unless I had money to burn.

Re: Largest bore....

Eventually you're going to run into diminishing returns due to airflow limitations. Keep in mind that the head was originally designed for a 1600 cc engine.
