Stop in for a cup of coffee

The thing i don't get in the auto industry is things like my rocker **** last night "Every head is different" No... they really shouldn't be. .this **** is CNC machined every single head should be exactly the same.. every rocker riser on every head should be exactly the same distance over and over.. that's the entire point of CNC to take out the human **** up element...

I worked for a company doing heads for caterpillar.. this was 25 years ago and every hole was machine drilled and pre-programmed, no 2 heads were different...
