not something I'd be all that willing to try either First off he wants you to Mill the head down to raise the compression Then turn around and cut at least .005 groove to lower the compression back down by 1cc.
If piston to head is at .070 Or .040 as he said he has run that close. How Close are the valves to piston???? Surely makes me wounder. He also does states You can Hit water If things are not checked Before cutting the groove Hummmmmmm Really makes one wounder doesn't it???????
One Other funny thing I read Is that he wouldn't do a Dyno Test UNLESS someone Else Pays for it??????????????
I have a fire slot cut into my Dome pistons But not something I'd be to willing to do to my heads something about that don't really seem right,and Like french said what about carbon build up in that slot what happens over time there????? carbon is pretty hard. And the compression I would think could very easily crack The head In that V groove you now have cut into the head esp. if for some odd reason it ever Back fired????? Or what if someone desides to add some NOS
Just my 2cent thoughts.
God doesn't like ugly.
