I bet if you were to use a set of Manely Race-Flow or Street Flow valves (with the necked down stems) you could pick up some decent numbers witout any porting for those afraid to grab the grinder.
Add that to a slight enlargement & polish of the exhaust ports & a good gasket match and cleaning up the intake casting flaws might make these heads produce some good numbers without even cutting for the larger valves.
