Wow! You guys can't believe how much better I feel about my build after reading this! My valvetrain noise has been bothering me all summer. I kept thinking about swapping out the lifters this winter. I know my pushrods are also a little on the short side but they seem to be working fine with adjustable rockers. I am running a Voodoo and it has "some" noise. I wouldn't call it horrible, but the stock cam, lifters, rockers were whisper quiet, so I figured I did something wrong!
