You can take out the cone, but then nothing keeps the pin that rides on the cone from being pushed out by the fuel pressure, so you get a nasty fuel leak.
The lever that pushes the pin that rides on the cone bottoms out before the pin makes it to the deepest part of a modified cone, however.

I don't see what the benefit in it would be. I imagine it would make it perform like crap and be really hard on the pump.
Delivery valves on a VE aren't as significant a restriction as on a P-pump, and it's kinda important to keep residual pressure in the injection lines. Or so say the people that built the things...

that's actually false. the injectors are held closed by spring pressure. DV's or not; a drippy injector is an injector problem: not DV problem. the other guys are correct tho. its meant to hold a residual pressure on the lines. only about 200 psi it may be less for the VE as i believe that spec may have been for P style pumps if i remember correctly... i kind of slept alot thru my diesel performance and diagnosis class. this residual pressure drastically cuts down on beginning of injection delay and allows much more accurate injection timing. you dont have to "wait" for the pressure to build. also the DV acts as a check valve and in the closing action of the DV it reduces line pressure for an abrupt closing of the injector nozzle rather than it "bleeding off" until fuel quits delivering which could be considered the "dripping" in between injections that cumminskid was talking about.
