No i wouldn't and the reason is the air velocity would be to low for the 408 and too high for the 632. I liken it to sucking on a straw where my mouth is the piston, the straw is the port and my finger covering the end of the straw is the valve. How far i move my finger from the straw, how fast i move it and how long i hold it away affects velocity. I will dig out my book and take a look, i guess i missed that section somehow.
