Is it possible to not modify the sprinkler valve (Blowgun Modified Sprinkler valve) in a spud gun? if so, disadvantages? Answered

so, what i am trying to say is, i want to use a regular sprinkler valve instead of a modified one in my spud gun Project. Can i do that or do i have to modify the sprinkler valve? if i can, will it reduce the power of the shot?
