I have run cut wiseco's and cut cast pistons with good results . I used the cast pistons while the new wiseco's were being made . I did 600km of hard racing on the cast cut
pistons and can show a picture of what they look like . I changed them to be safe but looking at them you would say they are good to go . My new motor runs full skirt wiseco's
with no problems . What i do is double check bore clearance , ring gap , counter sink oil holes , warm it up before you blast it etc .
