Hi Peter,
I am making an assumption that the valve in the photo was (polished) before trying in the guides .
if not then do that first then mount in a bench drill grip it with about 20mm in the chuck you will soon know if bent
make sure to clean under side of head including valve seat also seat in block ,then using fine paste just lightly lap in
this will also register on the valve in one place only if bent
hope that is of some help and it wont cost anything maybe frost bite
Cheers Colin
