has anyone removed the HPOP valve springs? results?

just like the title says. ive read around that removing the valve springs will equalize pressure between the lines at the pump, the same as adding another high pressure line to connect the two sides. ive read this would help to smooth out idle, and im wondering if anyone has tried this, without doing anything else, and can give some insight into any results.
also, is is JUST the springs that are removed, or are there little ball valves behind them that would need to come out also? thanks

I don't know anything about pulling any springs but if you want to smooth idle etc why not install the cross over line between the heads.

thats exactly what this is suppose to do. instead of buying a crossover line, removing the springs is suppose to equalize pressure at the pump, negating the need to add another line. i think most of the guys that build high peformance pumps toss the springs just for that reason. just wanted to hear from anyone that has tried this to see if it did actually make a difference or not.

Haven't done it, but would be interested to hear from anyone who has. Maybe I'll give it a shot before I send my pump in to termi for a rebirth.

This is what I did when I installed my Adrenaline HPOP. Per the instructions it does what you are thinking.

I'm assuming that after these are removed, you might have longer crank times. They hold HPO in the heads and don't allow it to bleed backwards.

honestly im just looking for a way to smooth out the idle of my truck.. its getting annoying as im not a kid anymore, but i just dont see the reason to drop money on a crossover line that will break when removing the valves would do the same thing. people with the crossover line are also welcome to post their experoence with it

what makes you say a crossover line will break? The stock hpop lines dont break that often.
