This advice given above is exactly wrong. More lash gives less duration and tighter gives more duration. More duration will enhance the top end and likely remove some from the bottom end. You must respect the manufactures intended valve lash and not deviate more than .010" either way, too louse a setting will hammer the lifter off the lobe causing damage.

X2....I know first hand about the roller damage. I used to think they would tighten up when HOT...of course this is
100% wrong but back then I didn't know...I set them cold just a little loose thinking they would be just right when hot....it's the opposite.I busted a roller lifter(and a block) after 20 something passes. live and learn.
