You can order differant (lighter) springs for the power valve. I'm not sure where to get them, though. Some people just cut them, but that's not a good idea. I am going to put dual Holley 94's on my 261 when I get it done and it's easier with those, you just put a differant cartridge valve in. I get my parts from www.vintagespeed.com, a multi-carb specialist.
