You may need to fold the ear flap a bit more to allow you to get it off.
See this is why you're smart, and I'm maybe not so smart. When I read this the first time, I had no idea wtf you meant. Now having done it, I know _exactly_ what you meant.
So here's the ingredients for the base gasket leak stoppage:

Unfortunately once I got started, I forgot about the camera, as I couldn't work out how to get the %^&%en ring compressor out after the cylinder went on. See the head studs, they are
in the way.
It was only once I worked out that you could sorta kinda squeeze the ear flaps between the stud and piston, and spin it around to get it outside the studs before pulling it out. Now if only I'd had the foresight to fold those ears in a bit more. Now who could possibly have mentioned that?
Anyway, all back together, with the head on temporarily with nuts torqued up to seat the gasket nicely.

And here's some of the threebond having squeezed itself out, to show I put maybe a tad more on than I should have:

So I celebrated by changing my brake and clutch fluid, which has been sitting around for 18 months:

Rather scarily, the contents of my whisky bottle look _exactly the same_ as when it had whisky innit. I guess that's how they make Islay single malt.
