U learn something new ...etc

Where can I get a key from??

Don't have my old cam, the engine builder put it in the bin when they rebuilt the head weeks ago (I think anyway).

I do have a spare head c/w cam but would rather keep it as is.

Oh yeah my pulley has KA stamped on it is that right?

New cam is in anyway but a bit stiff near the pulley end I hope its not worn and will just run in when back together...fingers crossed!
