Response to Chrono Results for 2240 Valve Extension and 1377 Valve Stem Exhuast Valve

Here you go in case you are interested. They flow alot more at higher pressures because of the reduced diameter of the stem and the poppet.


Here are a couple of photos of the valve with the 1377 stem installed:

If you are interested in the 1377 stemmed 2240 exhaust valve, it comes with a stem and the front half of the valve, shipped US Mail for $25. Antony's Pro-Top is not included........
