Anyone had problems with 1.60 valves on stock seats? I've searches a ton and it seems half of the people say 1.57 and the other say 1.60 is fine. These are 317 heads and I want a large exhaust valve because it's for a 370 blower motor but don't want to spend much on stock castings so I wan't to avoid putting in new seats and I am doing the porting myself. From measuring with a micrometer it doesn't seem that the 1.60's will fit but if people have used them I would like to put these in my heads.
