A valve clearance that's too tight will cause a loss of compression and likely result in a burnt out valve or valve seat.
A valve clearance that is excessively loose could eventually cause wear to the corresponding cam lobe.
A loose valve clearance is better than a valve clearance that's too tight.

With an insufficient clearance there'll be an increase in temperature at the valve seat caused by the combustion leak, the hot spots caused will eventually burn the valve and/or valve seat away. Worst case scenario, some of the valve head will fuse to it's seat and break away from the rest of the valve. Not a pretty sight once the piston has smashed it around the cylinder a few times.

Thats why the clearance is greater for an exhaust valve, the intake valve gets cooled by the intake air and fuel spray.
