We used stud girdles for head that were "a thousand years old" L88/ZL1 Chevvies to help the rocker arm studs (threads). That was fairly straightforward. However, when adjusting the valves you are constantly chasing your own tail, cos the girdles bend the assembly slightly every time you tighten it.

What I am saying is: This is very old school. And not the best part of it.

As for cross bolting mains (for your Ford) I can also refer to the Can-Am ally chevies, which had 4-bolt mains. And could take 1.000 hp (today), which was similar to having turbos back then.

I admit, they did not race 24 hours like a GT40, but will you?

Post a pic of a Ford with stud girdles. I am curious to see.
