BIY did a similar thing a few years back when they turned a 4 cylinder head into a 5 cylinder head.
Like you say. It's incredible that it can actually be done at all.

That looks interesting - I like the sound of a straight 5
I notice they sent the parts to a machine shop to have them cut - Allen Millyard used to rely on a hacksaw and file!
