I'm 1/2 way through the engine rebuild of my Euro 3.2L

I want to keep costs down so I'm planning to undertake as much work as possible. I have access to a machine shop so I'm considering DIY twin plugging and boring the crankcase for 100mm cylinders.

Questions:

On this forum I have seen references to chamfering the heads, is this a 45deg bevel to match the 95mm head to 100mm cyl'd ?

Does the mating surface between the head and cyl'd need enlarging to match the 100mm cyl'd ?

As there is no gasket at this joint what sort of surface finish should I be aiming for ?

Has anyone got an old head to practice on I am prepared to pay for it and the shipping to the UK.

To all you UK readers has anyone found a quality machine shop in the UK who can undertake valve guide replacement and valve seat cutting ?

thanks for all the help you guys give, it's a great site.
