Default Does a cooling system pressure test show if you have a vacuum leak?

Im trying to check if i have any vacuum leaks in my car's engine. I tried the carb cleaner method where you spray vacuum lines and suspected leak places in the engine but i want to try a more accurate way...or rather a different method.
I've been hearing about a "cooling system pressure tester" but im not sure if that's just for detecting leaks in the radiator or the entire engine. So, does a "cooling system pressure test" work for finding "vacuum leaks"...and perhaps also a blown head gasket?

Yes you can find a blown head gasket with a pressure tester.
No it will not help you with a vacuum leak.
As far as other methods you can use a Evap smoke machine or propane and a scan tool.
