Brain,
Here is the thread where it was mentioned that LG recommended a max cut of .080".

I've seen preople cut up to about .140" deep successfully.
There is about 1/4" (.250) meat on the piston top. You might be ok, just make damn sure you never run lean!
And serious, it's time to put the drill down and use something a little slower, ie: tap wrench or air ratchet. (those notching tools were actually designed to be used by hand).

Fly Cutting
Okay Guys this is what I found out. The actual piston thickness is.360. and one guy actually measured it to be 8 mm. The cut I made is .164 the rest .120 intake, that gave me clearance of .085. Exhaust .125 for a clearance of .100 So maybe it will be alright. Great tip about running lean . Start up in 2 days so then we will see Thanks
