Dennis,
Depends on the application(Pure race looking for the last .01).
When the 2.19 or 2.25 and 1.88 valves were put in hopefully they made
a plunge cut down into th ebowl area. If they did I would just blend
it in if they didn't. Outside of that you would be chasing small
gains for larger money. Most large oval ports with a plunge cut and
larger valves flow very well.
