Engine Technical Specs

Hello

Is anyone able to tell me the tolerance/clearance for the valve stems to the valve guides ?
I have all the valves out and properly measured, I have also measured the guides with a tool and have calculated all the values. I want to know what the tolerance is . Valve stem is near to 7mm, what is the internal bore of the valve stem ?

I think a regular engine would be about 50 microns, does anyone know what the tvr spec was, is

Thank you
