i'm sure cams like the Ms4 don't even have that kind of clearance. But yeah I agree, that does sound way close. To close to even thinking about relying on good springs to save your ***.

You'd be surprised how many people are running with that tight of clearance and don't even know it. Some never have contact while others have contact but never know it. If you like the cam, it's best to flycut for peace of mind or retard the cam a degree or two then re-measure.
