best flowing valves

For stock size , the best way is to make them out of stock valves. Cut them off as small a diameter as you can and still have full seal on the seat. Face them off till there .030 or .040 thick on the edges, then undercut the stems to reduce air flow restriction while also lightening. You can get rid of a lot of weight if valves are a not a tec item. Undercutting the stems will do the most for airflow. Jon
 
I believe limited just puts a limit on the bore, stroke, carb and other things like that, not the valvetrain or cam
