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.
Whiplash has .544 lift and all that's needed is to run the matched valve springs and the set of retailers that Hughes calls for. It's a bolt in/on cam. No machine work needed to any parts. And as long as it's installed to the card (installed centerline of 104), there's no risk of piston to valve contact either.
Edited my original post to include that figure is on stock valve springs and retainers.
