It was a decent size shoehorn, yes.
We had to pretty much clear out the engine bay bar the engine itself, although a lot of gear came off that as well, and then build it all up again.
But it's still the original engine, the head has never been off, and can shave a set of wheel studs off by just looking at the go pedal.
The biggest issue created with the install is it makes my face ache from grinning all the time.
