Generally the seat wears more in the middle,leaving a concave seat,,
The valve wears convex as a result,,
They will sort of mate if left undisturbed,,in their travel
If the travel is disturbed they are not so likely to seal
Rock and a hard place,,,
I expect most of us hobbyists will still be using English measure
Not sure on this,,assumption on my part,,I have 1--7" mikes and
a 4' [48"] Vernier,,and just a small MM mike,,Dial gauges all
English measure
There is not a lot of "meat" in the valve chest
For that matter there is not a lot of extra iron anywhere on the car,,
All for now,,Cheers,,Ben
