I know for sure there is a thread here about that. I don't know of a current website with the info on it. If you search there's a good thread that had photos and all. It must be over a year old by now though. Good luck!

It's really not that difficult but I'm not sure what most folks here use to spin the cutter valve with the engine up under the cowl. I'm guessing a good 90 degree drill. Anyways, you basically replace the stock valve with a valve that has a cutter ground into the face of it. You usually run the piston to TDC, install the head with cutter, push down on cutter until it touches top of piston, set tool depth(I use a feeler gauge in between collar and valve guide boss to set my collar which is set screwed to the valve stem), drill until collar touches the top of the valve guide. I've always used a spare head to do this with so I wouldn't mess up the top of the guides or valve seats.
