How do you test an internal wastegate?

POP!
Blew a headgasket last week - the wastegate didn't open at 8 psi.

If I use a syringe and force about 8 psi of pressure into the wastegate, is that a good way to test it?

I used my air compressor with an air regulator.

I unhooked the CO2 tank from my homemadekegorator, set the gauge at different pressures and watched that the wastegates did actually open at 10 psi.
