Both - thanks.
So from Terry's pic... that looks like slightly less than 45 degrees and seems to be slightly asymmetrical removal towards one valve type?
The Williams book makes it look huge... I'm presuming for standard Austin pistons a couple of mm depth. (I cant see the piston edges cos they are in the engine)
