I just had a thought, .. yea , yea I know, .. it's rare.

While talking about "stage" porting, etc, .. THE MOST important part of this level of modification has not been talked about, ..
the valve job. With limited port work the valve job is the larger portion of what you should be paying for at this stage, ..
so porter dudes, .. what are you doing for valve jobs?

Just the standard 3 or 4 angles, .. custom cutter sets, .. ?????

This is by far the most neglected area. I get these CnC heads in from name companies, .. AFR, Dart, etc, .. don't want to
pick on the CnC porting cause it's often fairly good, .. but the valve jobs often SUCK! A few hours on the seat machine, touch up with a grinder and the heads pick up a bunch, .. other experience ??
