The answer ot enlargening the threads is so simple you might not believe it.
Dig out an old tap of the appropriate tpi and grind it back short enough that the tapered end is removed. If you happen to have a bottoming tap in the correct tpi, it might work for this without grinding back. I used a regular tapered tap. Now use the tap like a scraper to deepen the existing threads. Slowly work your way around taking care to keep the tap threads lined up on the old worn threads as you go.

SWEET! Who'd a thunk it!
Thanks for the tip Glen.

Thanks for the comments Guys! Yeah it was a thread file I used to clean the threads like this one




I clamped the head to the workbench and worked the scraper end round the inside with sufficient force and a little patience it easily follows the remants of what thread is left untill you get somthing resembling a decent thread.
In regard to the single chunky lug for tightening purposes I have never had trouble apllying enough tourque to grunt the nuts up, I have been using this rough looking lug spanner for years, either use a length of tube or a hammer and you cant go wrong!
I like the look of the beemer tool though.





Now I am not suggesting that my methods will work for everyone and as for the long term prospects only time will tell!

Glad I asked thanks for the clever tool eye candy swoosh. Rip and Ken opened my head on the alloy info. Nip em up when head hot and heat up head to take em out. Like the shorty mobel Capt Hook or more tradition caveman club length best to impact with a sledge to rattle shock a rim wave off adhesion so no mere violent engine vibration can. I've sworn off gaskets of any kind d/t crush and rattle wear. If you've ever seen a fastener clamp force holding tester machine for types of washers or none at all, the Norton exhaust bolt is about only real life example I know that can match that testers tourture but w/o the thermal effects thrown in, so maybe worse in real life. Build em rugged and treat em rough is how they like it best. This is part of what expanded my images of solid state physics - real life metal that's flexible expandable and elastic.

I've a photo not posted yet of my kit that looks too much like USSR hammer and sycyle.
