Are all valve cores the same size?
Condensed answer: Presta valve cores are universal. Some models are more sophisticated than others, but in most cases, the cores are interchangeable as they’re the same size and use identical threading.

What is the valve margin?
Intake valves should have a margin of about 0.050 inch, and the edge should be sharp where it transitions to the face of the valve. Exhaust valves are a different story. The margin for an exhaust valve should be larger to improve heat dissipation—generally around 0.080-0.100 inch.
How do you measure valve clearance?
Position the dial indicator on the top of the exhaust-valve retainer and zero the dial indicator. Next depress the exhaust valve. Note the distance traveled. Now subtract the difference in the gasket thicknesses and you should have an accurate measurement of the piston-to-valve clearance.
