piston radial clearance

has any one had an ussue when going to 1mm oversized valves that the radial clearance is to close to the piston as the valve opens? if so what can I do to corret it. Ive been told that if the valves radial dosent contact the piston ill be good to go, im using a wiseco hd piston
