Hi all
Just about to re-cut my valve seats. I read that the depth should be 40.1mm, measured from top of valve stem to spring seat. What is the maximum permissable depth ?
Just want to avoid over cutting the depth, would normally just do a couple of turns to freshen up, but this head has been sat outside and has some pitting to the inlet seats.
