No prop valve I've ever seen or messed with even comes close to "closing all the way", they don't work that way anyway. They aren't an orifice that you control the size of, that would control flow, not pressure. Even the Wilwood valves state max pressure reduction. Most are 57 percent.

Isn't this essentially the same thing, but without the "racer" markup?

Thats how I currently do burnouts. But I like the brake down, flip a switch, brake up, dump clutch.
I've read lots of SS ball valve line lock stories. They all work and are cheap. off-road guys like em.

But doesn't it just close off the line?

I don't see why you can't use an off the shelf ball(or whatever) valve as long as it is good for the pressures it will see.
