with the wiplash cam do u have to cut the valve guides down?




stock guides are good up to .520" lift before you will smack the guide top.

Edit with more info; stock valve springs and retainers are only good to .520" lift. Hughes springs and retainers package for magnum heads will give anoth ".100" of lift allowance on stock magnum heads.
