TFS 290 and 325 heads exhaust valves

I got some tfs 325cc head and i ordered some ford racing tulip exhaust valves to replaced the one that come in the head, the ford racing ex valve messures just a little bigger on the stems, has anyone installed these valves without honing the guides . I dont want the valves to seize in the guides .

How much bigger?
What was the clearance with the old valves?

Cheers

I'd say hone the guides in order to get proper clearance. TFS intends for the stem to guide clearance to be .0016" with their Ferrea valves.
